How Much B12 In A Portion Of Beef Lasagne?
I asked Google AI, the title of this post and received this answer.
A standard portion of beef lasagne (approx. 200g-300g) typically contains between 0.6 mcg and 1.7 mcg of Vitamin B12.
This amount provides roughly 25% to 70% of the recommended daily intake (RDA) for adults (which is 2.4 mcg).
Per 100g: A 100g serving contains approximately 0.3 mcg to 0.4 mcg of B12.
Higher-End Estimates: Some nutritional data indicates that a generous, nutrient-dense serving of homemade beef lasagne can have as much as 1.7 mcg of B12.
Source: The primary source of B12 in this dish is the ground beef, with additional amounts from cheese and dairy.
Note: The exact amount depends on the amount of beef and dairy used in the recipe.
I generally eat, one Marks and Spencer’s Made Without gluten-free beef lasagne every week.
Does Lack Of B12 Affect Your Hearing?
I asked Google AI, the title of this post and received this answer.
Yes, a lack of vitamin B12 can affect your hearing, potentially leading to tinnitus (ringing in the ears) and hearing loss. Deficiencies can cause nerve damage (demyelination) in the auditory nerve and damage the small blood vessels in the inner ear.
Impact on Hearing
Tinnitus: Studies suggest B12 deficiency is linked to tinnitus, with some research indicating that supplementation can improve or reverse these symptoms.
Hearing Loss: Low B12 levels are associated with a higher prevalence of hearing impairment, particularly in older adults.
Inner Ear Damage: A lack of B12 may cause degeneration of the cochlear nerve.
Developmental Issues: In children, B12 deficiency may interfere with auditory development.
Causes and Risk Factors
Deficiency can result in high homocysteine levels, which may impair blood flow to the cochlea.
Risk factors for low B12 include:
Vegetarians/Vegans: Due to limited dietary intake.
Adults Over 60: Due to reduced absorption.
Digestive Disorders: Conditions like Coeliac or Crohn’s disease.
Medications: Long-term use of metformin or antacids.
If you are experiencing persistent tinnitus or hearing changes, it is recommended to consult a doctor to check your B12 levels.
I fairly sure that my hearing fits that pattern. Although, I’ve never had tinnitus.
How Do B12 Levels Affect Pain In Knee Joints?
I asked Google AI, the title of this post and received this answer.
Low Vitamin B12 levels can cause or worsen knee joint pain primarily through nerve damage (peripheral neuropathy), which causes sensations of pain, tingling, or numbness in the legs. Deficiency also increases homocysteine, a pro-inflammatory amino acid linked to joint inflammation and, in some cases, accelerated cartilage deterioration.
Key Connections Between B12 and Knee Pain:
Neuropathic Pain: A lack of B12 damages the myelin sheath protecting nerves, leading to pain, pins and needles, or burning sensations often felt in the extremities, including the knees.
Inflammation and Joint Damage: Low B12 levels are associated with higher homocysteine levels, which can cause inflammation, swelling, and increased friction in the joints.
Deficiency Symptoms: Along with joint pain, B12 deficiency commonly causes fatigue, muscle weakness, and numbness.
Improvement with Supplementation: Studies suggest that maintaining adequate B12 levels, or using supplements, can reduce joint pain and improve mobility.
If you are experiencing persistent joint pain or numbness, it is advisable to have your B12 levels checked.
From my own experience, I would also get tested for coeliac disease.
Does Being Widowed Lower Your B12?
I asked Google AI, the title of this post and received this answer.
Widowhood does not directly cause a biological decrease in B12, but it is often associated with lifestyle changes and stressors—such as depression, loss of appetite, and reduced nutritional intake—that can lead to a lower intake of Vitamin B12.
Key points regarding the connection:
Nutritional Risk: Research suggests that older adults who are widowed or depressed may have lower intakes of various nutrients, including Vitamin B12.
Depression Link: Depression, which is common in bereavement, is significantly associated with lower plasma levels of vitamin B12.
“Undernourishment” Factor: Studies indicate that widowed individuals are frequently represented in groups at high risk for undernutrition, which can contribute to nutrient deficiencies.
Lifestyle Changes: The transition to widowhood often involves a loss of partner support, leading to poorer nutritional habits and neglect of self-care.
While being widowed is not a direct metabolic cause, it is a significant risk factor for conditions that lead to B12 deficiency in older adults.
I certainly, eat less Vitamin B12, than before my wife died, as when we had a meal in a certain pub in Suffolk or Carluccio’s, I always had calves liver or fegato.
Ocean Winds Enters Lease Agreement With Crown Estate For 1.5 GW Celtic Sea Floating Wind Project
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ocean Winds has entered into an agreement for lease with the Crown Estate for a 1.5 GW floating offshore wind project, for which the developer secured a site in the Round 5 seabed auction last year.
These two paragraphs add detail to the story.
Offshore Wind Leasing Round 5, the UK’s first dedicated floating wind seabed leasing round, was launched in February 2024, offering three areas. In June 2025, the Crown Estate announced Equinor and Gwynt Glas, a joint venture between EDF and ESB, as preferred developers for two project sites and said it was working to ensure the delivery of the full potential capacity of Round 5, which is up to 4.5 GW.
Equinor and Gwynt Glas entered into lease agreements for their floating wind projects in October 2025 and, the following month, the Crown Estate said Ocean Winds had secured the third floating offshore wind site in the Celtic Sea.
This map shows the three wind farms, that make up the Glynt Glas wind farm.
Note.
- It is expected to be built from and connect to the grid at Port Talbot in South Wales.
- The three sites are expected to be commissioned by the early-to-mid 2030s.
- The elongated white dot to the East of the wind farms would appear to be Lundy Island.
- The large bay to the North of Lundy is Carmarthen Bay with Caldey Island at its West end and Llanelli on its East.
- The Gower separates Swansea Bay from Carmarthen Bay.
This Google Map shows the Bristol Channel from the wind farms in the West to Cardiff and Hinkley Point.
Note.
- Along the North coast of the Bristol Channel, working from West to East, my 78-year-old eyes can pick out Milford Haven, Pembroke, Caldey Island, Tenby, Llanelli, Swansea, Port Talbot, Porthcawl, BridgendCaerphilly, Cardiff and Newport.
- Coming back along the South Coast, I can see Weston-super-Mare, Hinkley Point C and the tip of Lundy Island in line with Tenby.
- The three sections of Glynt Glas will each generate 1.5 GW, making a total of 4.5 GW.
- Hinkley Point C when completed, will be a 3.26 GW nuclear power station.
- There is also a 2.2 GW gas-fired power station at Pembroke.
Nearly 8 GW of renewable electricity should be enough to convert Port Talbot steelworks to the manufacture of green steel.
How Much Wind Power Is Planned For The Western Approaches?
I asked Google AI, the title of this section and received this answer.
The UK has a target of 50 GW of offshore wind by 2030, with significant projects planned for the Celtic Sea (part of the Western Approaches), which is a key area for 5 GW of floating wind. Total UK offshore wind pipeline capacity exceeds 93 GW, with major developments in this region focusing on floating technology.
Key details regarding wind power in the Western Approaches (specifically the Celtic Sea) include:
Celtic Sea Developments: The area is a primary focus for floating wind projects, designed to capitalize on deep-water potential, with 5 GW of floating wind expected to be deployed across the UK by 2030.
Pipeline and Capacity: The total UK pipeline for offshore wind, which includes the Western Approaches, is 93 GW, and the government is aiming for 43-50 GW of installed offshore capacity by 2030.
Project Status: The region is expected to benefit from the Crown Estate’s leasing rounds aimed at accelerating floating wind, with 15.4 GW of new projects submitted across the UK in 2024.
Wales/South West England Context: Wales has 1.4 GW of projects in the pre-application stage, with some potential for developments off the South West coast.
For more detailed information on specific projects and their development status, you can visit the RenewableUK website and RenewableUK website.
It looks like about 20 GW of offshore wind could be installed in the Western Approaches.
If You Lack Vitamin B12 Is It Sensible To Limit Alcohol?
I asked Google AI, the title of this post and received this answer.
Damages Absorption: Alcohol irritates the lining of the stomach and intestines, which hinders the digestive system’s ability to absorb Vitamin B12 from food or supplements.
Reduces Storage: B12 is stored in the liver. Chronic alcohol use can cause liver damage and inflammation, reducing the liver’s ability to store and release B12 when needed.
Impairs Function: Even moderate amounts of alcohol (one or two drinks a day) can interfere with B vitamin levels.
Increases Deficiency Risk: Research indicates that B12 deficiency is common in individuals who consume high amounts of alcohol.
Severe Symptoms: Increased fatigue, neurological issues (numbness, tingling), and cognitive problems.
Irreversible Damage: Long-term, unaddressed deficiency can lead to permanent nerve damage or severe anemia.
Recommended Steps:
Limit or Stop Alcohol: Drastically reducing alcohol intake allows the digestive system to recover and improves absorption.
Supplementation: If you are treating a deficiency, your doctor may recommend B12 supplements (pills, nasal sprays, or injections).
Dietary Changes: Increase consumption of B12-rich foods like red meat, fish, poultry, eggs, and dairy, or eat fortified foods.
How Much Electricity Do You Need To Charge A Garage Full Of Electric Buses?
Consider.
- A couple of years ago, I had a long discussion and a few beers with three managers of bus garages.
- In First Bus To Launch 1MW BESS Unit In Hampshire, Aberdeen To Follow, I talk about a specialist battery to charge buses.
- In Is Sumitomo Heavy Industries Highview Power Energy Storage System On line At Hiroshima?, I talk about an efficient, renewable power supply for an LNG Terminal.
I asked Google AI the question in the title of this post and received this comprehensive answer.
Charging a full garage of electric buses requires massive amounts of electricity, with typical, non-optimized charging for a 100-bus depot capable of drawing nearly 10 megawatts (MW) of power. To put this into perspective, a 100-bus depot might require roughly 150 Megawatt-hours (MWh) of energy to recharge over an eight-hour night.
Key Factors and Energy Requirements
Energy Consumption per Bus: A typical electric bus has a battery capacity between 300-500 kWh. Energy consumption averages around 1.11 to 1.35 kWh/km, with higher consumption in winter or with heavy A/C use.
Total Depot Power: For a 100-bus depot, power requirements can reach 10 MW, equivalent to the power output of a small hydroelectric dam.
Optimal Charging: Using smart charging, a 100-bus depot can reduce its peak demand to around 4 MW.
Daily Usage: A single, large electric bus can consume up to 500 kWh per day, with daily demand ranging from 189 to 231 kWh for typical operations.
Infrastructure and Grid Considerations
Charging Infrastructure: Depots often use 40 kW to 250 kW chargers, with 100 kW common for overnight charging.
Grid Capacity: A 34-bus depot might require a new 1000kVA transformer to handle the load.
Voltage: 11,000 volts may be required to power new substations, which are then stepped down to 400 volts for charging.
Operational Factors Affecting Energy Need
Heating and Cooling: Cold weather can increase energy consumption by up to 45% (due to electric heating).
Driving Style: Inefficient driving can increase energy consumption by 0.24 kWh/km above average.
Regenerative Braking: This can recover 37–40% of energy for 40-60 ft buses.
Cost Implications
Energy Bills: A 100-bus depot can incur monthly energy bills between $112,000 and $515,000 without optimization.
Cost Savings: Electric buses are generally cheaper to fuel, costing ~£0.21/mile compared to £0.49/mile for diesel.
Could A System Based On The Sumitomo/Highview Power System At Hiroshima Charge Electric Buses?
The optimal charging figure for a 100-bus garage would appear to be in the region of 4-5 MW.
In Is Sumitomo Heavy Industries Highview Power Energy Storage System On line At Hiroshima?, I state, that it looks like Highview Power’s CRYOBattery™ at the heart of the system has a capacity of 5 MW/20 MWh.
I also state in the post, that the Hiroshima facility is designed to support grid stability and enhance renewable energy integration.
Does this all mean that if you can install enough solar panels on the roof of the garage or perhaps a wind turbine nearby, that you can have buses substantially powered by the sun and wind.
Chicago would just love wind-powered buses!
Is Sumitomo Heavy Industries Highview Power Energy Storage System On Line At Hiroshima?
From some work I did at ICI in the 1970s on a PACE231R analog computer, I believe that Highview Power may have an extremely promising way of storing energy.
The Highview Power web site talks of Sumitomo Heavy Industries, who are building one of Highview’s batteries at Hiroshima in Japan.
So I asked Google AI the question in the title of this post and received this comprehensive answer.
Yes, the Sumitomo Heavy Industries (SHI) Highview Power liquid air energy storage (LAES) commercial demonstration plant in Hatsukaichi, Hiroshima, is operational, having commenced operations on December 1, 2025.
Key details about the plant:Location: Within the Hiroshima Gas Hatsukaichi LNG Terminal.Capacity: 5 MW output with 4-hour storage (4 MW charging).Technology: Uses Highview Power’s CRYOBattery™ technology, specifically utilizing waste cold from the adjacent LNG terminal to improve efficiency.Role: The facility is designed to support grid stability and enhance renewable energy integration.A completion ceremony for the project was held on December 9, 2025. This news item from Sumitomo Heavy Industries gives more details.This paragraph describes Liquid Air Energy Storage or (LAES).
- It looks like the battery has a capacity of 5 MW/20 MWh.
- As it talks about using waste cold, this looks to be a very professionally-designed specialist application.
- But surely, that would be expected from a company like Sumitomo Heavy Industries.
There are hundreds of LNG terminals globally, with significant growth driven by over 300 projects (roughly 177 import/regasification and 124 export/liquefaction) expected between 2025 and 2030. In 2023, there were 22 countries with active liquefaction (export) capacity, while Europe alone operates roughly 28 large-scale terminals, supplemented by a rapidly expanding fleet of FSRUs.Export Capacity: In 2023, global liquefaction capacity was 472 million tonnes per annum (mtpa), with top exporters being Australia, the U.S., and Qatar.Expansion: By 2027, 52 new liquefaction terminals are expected to commence operations.Import Growth: European regasification capacity is expanding, with major terminals in Spain, France, Italy, and new additions in Germany and other nations.U.S. Infrastructure: The U.S. alone has more than 170 LNG facilities performing various services.
- They are listed in this Wikipedia entry.
- There are around thirty in Japan alone.
- Will Centrica add a 5 MW /20 MWh Highview Power battery to their Grain LNG Terminal?
- Each facility installed is claimed to be designed to support grid stability and enhance renewable energy integration, so the last part must cut carbon emissions.
Yes, several major chemical engineering and industrial processes generate significant amounts of “waste cold” (low-grade thermal energy or cryogenic energy) that is often discarded. While the chemical industry conventionally focuses on recovering waste heat, recovering waste cold is becoming increasingly popular for improving energy efficiency, particularly in cryogenic processes.

How Much Pumped Storage Hydro Will Be Operational In The UK By 2030?
Pumped Storage Hydro is the Bank of England-standard for energy storage.
I asked Google AI, the question in the title of this post and received this answer.
The UK currently has approximately 3 GW (roughly 26-28 GWh) of operational pumped storage hydro (PSH) capacity. By 2030, this capacity is expected to increase, driven by new projects in the pipeline that aim to meet a government goal of up to 8 GW of long-duration energy storage by that year.
Key Projects Expected Online by 2030-2031:
Coire Glas (SSE): A major project in Scotland with a planned capacity of 1.3 GW / 30 GWh, expected to be operational around 2030–31.
Cruachan Expansion (Drax): A 600MW plant in Scotland that has received approval, with construction expected to contribute to the 2030 goal.
Glenmuckloch: Projected to be operational by 2029. In
Other Developments:
Total Pipeline: Developers have identified up to 10 GW of potential projects in the Scottish Highlands and Wales, though not all will be operational by 2030.
Future Growth: The total installed capacity of PSH is expected to grow significantly, with one projection suggesting a rise from 26.7 GWh currently to over 122 GWh by 2034.
To support these projects, the UK government has confirmed a “cap and floor” investment framework to stimulate development of long-duration energy storage (LDES).
For a relatively small island we do seem to be an ideal place to develop pumped storage hydro!
The Coire Glas Pumped Storage Scheme
In The Coire Glas Pumped Storage Scheme, I give more details of this scheme.
The Glenmuckloch Pumped Storage Scheme
In The Glenmuckloch Pumped Storage Scheme, I give more details of this scheme, which is based on a disused open cast coal mine.
Addition Of Pumped Storage Hydro By 2030
This looks to be around 5 GW, but it is just a foretaste of the shape of things to come!
Could The Settle And Carlisle Be Used As A More Formal Route?
In June 2021, I wrote Through Settle And Carlisle Service Under Consideration, which starts like this.
The title of this post, is the same as that of an article in the June 2021 Edition of Modern Railways.
This is the first paragraph.
Plans for a new Leeds to Glasgow through service via the Settle and Carlisle line are being developed, with CrossCountry and the Department for Transport starting to look at the possible scheme.
It sounds like a sensible idea to me.
The article also suggests the following.
- CrossCountry is a possible operator.
- CrossCountry are keen to improve services between Leeds and Glasgow
- The trains could be InterCity 125s, freed up, by a the arrival of Class 221 trains from Avanti West Coast, when they receive their new Class 805 trains.
- Maintenance of the trains wouldn’t be a problem, as this could be done at Neville Hill in Leeds or Craigentinny in Edinburgh.
- Services could start in December 2023.
But nothing more has been heard.
However some things have happened.
The Settle And Carlisle Has Become A Popular Charter Route
Google AI gave me this paragraph.
The Settle and Carlisle line is an extremely popular, premier route for heritage rail charters, steam excursions, and luxury rail tours in the UK, often operating at full capacity. Renowned for its scenic 72-mile journey through the Yorkshire Dales and Pennines, it features iconic structures like the Ribblehead Viaduct.
I have also written these posts about charters on the Settle and Carlisle Line.
Scheduled Steam-Hauled Services For the Settle And Carlisle Railway
Rail Operator Crosses Line For First Time In Years
‘Staycation Express’ To Return Along Full Length of S & C
It doesn’t appear that the numbers of charter trains are showing any sign of decrease.
LNER Has Ordered Class 897 Trains
When LNER took over the East Coast Main Line services, they had six main classes of trains.
- Five-car Class 800/1 bi-mode trains
- Nine-car Class 800/2 bi-mode trains
- Five-car Class 801/1 electric trains
- Nine-car Class 801/2 electric trains
- Seven-car InterCity225 trains
- Nine-car InterCity225 trains
Note.
- The five-car trains can run in pairs as ten-car trains.
- The Class 800 and Class 801 trains can run to destinations, that lack full electrification using diesel power where needed.
- Hitachi are developing battery-power for rail routes without electrification.
In 2023 to replace the InterCity225 trains ten ten-car Class 897 tri-mode trains were ordered from CAF, which will soon be in service, over all LNER’s network.
LNER Has Fully Electrified And Unelectrified Destinations
LNER’s current destinations, that are fully electrified to King’s Cross include.
- Bradford Forster Square
- Berwick on Tweed
- Darlington
- Doncaster
- Durham
- Edinburgh Haymarket
- Edinburgh Waverley
- Grantham
- Keithley
- Leeds
- Newark Northgate
- Newcastle
- Peterborough
- Retford
- Shipley
- Skipton
- Stevenage
- Wakefield Westgate
- York
Whilst those are not fully electrified include.
- Aberdeen
- Cleethorpes
- Dundee
- Grimsby Town
- Harrogate
- Huddersfield
- Horsforth
- Hull
- Inverness
- Lincoln
- Middlesbrough
- Sheffield
- Sunderland
- Thornaby
- Worksop
Note.
- Other destinations can be added as required.
- I suspect, that Class 897 trains will be able to approach many stations without electrification on battery power alone.
- Staff and Passengers would probably like underground stations like Sunderland to be worked on batteries alone.
The Class 800 bi-mode, the Class 801 electric and the Class 897 tri-mode trains will give LNER a very flexible fleet.
Onward To Skipton, Carlisle and Glasgow Central And Edinburgh From Bradford Forster Square
I wonder is someone has realised that the Class 897 trains could use their tri-mode capabilities to invade Scotland?
This OpenRailwayMap shows the railways between the Scottish Lowlands and northern England.
Note.
- Red tracks are electrified.
- Black tracks are not.
- The blue arrow in the middle of the map indicates Carlisle.
- The red track going North-South through Carlisle is the West Coast Main Line.
- The black track going South from Carlisle is the Settle and Carlisle Line.
- Where it turns red is at Skipton station and the electrification can power the train to Bradford Foster Square, Doncaster, Leeds or Sheffield stations.
- The West Coast Main Line splits North of Carlisle and electrified trains can reach either Glasgow Central in the West or Edinburgh Haymarket or Waverley in the East.
- The black track going North-South between Carlisle and Glasgow via Dumfries is the Glasgow South Western Line, which can be used as a diversionary route by some trains with a self-powered capability.
The Settle and Carlisle Line certainly makes Anglo-Scottish routes more robust and flexible when there is bad weather, engineering works or overhead wire or signalling failures.
Will Class 897 Trains Be Able To Run On The Settle And Carlisle Line?
I asked Google AI this question and it gave this answer.
Yes LNER’s new Class 897 tri-mode trains (scheduled for introduction from 2027) will be able to run on the Settle and Carlisle line. As tri-mode electro-diesel multiple units, these 10-car trains are designed to operate across the entire LNER network, utilizing electric, diesel, or battery power to manage non-electrified routes like this, providing a modern alternative to older, diesel-only fleets.
Key details regarding Class 897 on the Settle and Carlisle Line:
Tri-mode Capability: These trains can run on electric, diesel, or battery power, making them highly versatile for non-electrified, scenic, or challenging routes.
Operating Strategy: The trains are designed for flexibility and can be used across the LNER network, which includes routes connecting to Scotland via the West Coast Main Line (WCML) or through services from Leeds.Upgrading Service: They will replace the 40-year-old InterCity 225 fleet, offering a more environmentally friendly, modern alternative to current diesel bi-modes, such as the Class 800/802.
The route is a major, yet challenging, rail line featuring 20 viaducts and 14 tunnels, making it suitable for modern, versatile train sets.
I also believe that running Class 897 trains between Yorkshire and Glasgow offers opportunities to run new services, that will appeal to both travellers and rail operators.
Does The UK Need More Passenger Rail Capacity Between Yorkshire And Glasgow?
I asked Google AI this question and it gave this answer.
Yes, the UK requires more passenger rail capacity between Yorkshire and Glasgow due to severe overcrowding and forecasted demand growth. Major routes like the East Coast Main Line (ECML) and West Coast Main Line (WCML) are, or will soon be, at maximum capacity. Key constraints include infrastructure limitations and the need for better Scotland-England connectivity.
Key insights on this need:
Capacity Constraints: The WCML, particularly at its southern end, is already effectively full, with limited capacity for additional, longer trains. Similarly, the ECML is experiencing significant overcrowding.
Growing Demand: Passenger demand for long-distance rail travel continues to rise, with significant increases noted in journeys between Scotland and other regions.
Infrastructure Issues: Constraints include steep inclines, tight curves, and the need to mix passenger and freight traffic, particularly on the West Coast route.
Proposed Solutions: While some improvements are planned, such as Lumo extending services to Glasgow, the Integrated Rail Plan (IRP) focuses on capacity enhancements in the North/Midlands.
Strategic Need: Enhanced, high-speed connections are considered essential for long-term economic integration and to prevent increased air travel/emissions.
The great advantage of the route, is that is already in place.
Can The Settle And Carlisle Line Handle Planned Diversions?
Can The Settle And Carlisle Line Handle The Caledonian Sleeper?
I asked Google AI this question and it gave this answer.
The Settle-Carlisle line is not a standard route for the Caledonian Sleeper, which typically travels via the West Coast Main Line (WCML) to Edinburgh, Glasgow, and beyond. While the line is a scenic, double-track route with significant infrastructure, it is generally used for local services and freight, not long-distance, heavy sleeper trains.
Key Considerations:
Route: The Caledonian Sleeper operates on the West Coast Main Line, serving destinations like Edinburgh, Glasgow, Aberdeen, Inverness, and Fort William.
Capacity & Infrastructure: While the Settle-Carlisle line has major structures like the Ribblehead Viaduct, it is not the primary route for high-speed or overnight sleeper services.
Operational Normal: The sleeper service splits into portions at Edinburgh, and does not regularly operate via the Settle-Carlisle line.
In short, the Settle-Carlisle line is not designed for or used by the Caledonian Sleeper, which operates via the West Coast Main Line.
But it does appear, that in the past some sleeper trains have used it.
How Many Freight Trains Use the Settle And Carlisle Line In A Typical Day?
This article on the BBC is entitled Settle To Carlisle line: Shortage of trains ‘Hampering Growth’, says this about the number of trains.
From only two trains a day in the 1980s the Settle and Carlisle line now sees 14 passenger and 18 freight services a day.
That is progress!
