Arriving In Liverpool Lime Street Station – 10th May 2025

Liverpool Lime Street station has one of the more spectacular approaches of British railway stations, as these pictures show.

These sections describe the approach.

Crossing The Mersey

You cross the Mersey at Runcorn on the Ethelfreda or Britannia Bridge, which is described in this Wikipedia entry.

It was completed in 1868 and hopefully in a few years, it will be carrying High Speed Two trains between London and Liverpool.

On your right as you cross the Mersey to Liverpool is the Silver Jubilee road bridge, which is a through arch bridge that opened in 1961 to replace a historic transporter bridge. I am just a little bit too young to have seen the transporter bridge.

Further to your right, you can see the Mersey Gateway Bridge, which is a cable-stayed bridge, that opened in 2017 and is described in this Wikipedia entry.

Drax’s Biomass

As you approach Lime Street station, you pass through Edge Hill, where there are the GB Railfreight sidings, where the biomass trains for Drax power station are marshalled for their journey across the Pennines. These Drax trains seem to be one of the few freight trains in the UK, that carry advertising. Tesco trains also do, but their’s is just big letters.

In Do Cummins And Stadler Have a Cunning Plan?, I talked about the possible conversion at some date in the future of GB Railfreight’s new electro-diesel Class 99 locomotives to electro-hydrogen locomotives. These locomotives will surely be ideal for hauling Drax’s biomass trains across the Pennines.

I do believe that these Class 99 locomotives are the future of heavy freight trains in the UK. In Iarnród Éireann Looks At Diesel Loco Replacement Options, I write about speculation, that Stadler may build a version for the Irish.

Through The Edge Hill Cutting

From Edge Hill a deep cutting through the sandstone takes you into Lime Street station.

It looked good in the sun, but the first time I arrived in the city to start my studies at Liverpool University, it was chucking it down and the cutting was very dark and wet.

It was a very different welcome to that, which I got yesterday.

My Train Arrived In Platform 10

Liverpool Lime Street has two cast iron train sheds.

  • The Western shed has platform 1 to 5 and generally handles trains from the East.
  • The Eastern shed has platform 6 to 10 and generally handles trains from the South.

Note.

  1. Changing between trains is just a step-free walk across the station concourse.
  2. Both sections have their own taxi rank and full-size clock.
  3. The Ticket Office is in the Western train shed.

I just walked from my train to the Ticket Office, bought a Lancashire Day Ranger ticket and then walked fifty metres to my next train.

How many stations have such an easy change of trains?

Is Liverpool Lime Street Station Ready For High Speed Two?

Consider.

  • I travelled North in an 11-car Class 390 train, which is 265.3 metres long and can carry 607 passengers.
  • As the last pictures show, the train fitted easily into platform 10.
  • High Speed Two plans to send 200 metre classic-compatible trains to Liverpool Lime Street, with each having a capacity of up to 528.

It looks to me, that these High Speed Two classic-compatible trains will fit into Liverpool Lime Street station, at any platform that currently accepts an eleven-car Class 390 train.

Looking on Real Time trains over the last few days, I’ve found eleven-car Class 390 trains using platforms 9, 10 and 6.

It seems that Network Rail’s engineers have done a superb job to turn the Grade II Listed station, into one of the best operationally.

Ørsted Receives Development Consent For 2.6 GW Hornsea Four Offshore Wind Farm

The title of this post, is the same as that of this article on offshoreWIND.biz.

This is the sub-heading.

The UK Secretary of State for Energy Security and Net Zero has granted development consent to Hornsea Project Four, a 2.6 GW offshore wind farm Ørsted plans to build some 69 kilometres off the Yorkshire Coast.

This is the first paragraph.

The UK government, in a press release issued on 12 July, stated that Hornsea Four was the 126th Nationally Significant Infrastructure Project and 73rd energy application to have been examined by The Planning Inspectorate within the timescales laid down in the Planning Act 2008.

It certainly looks like The Planning Inspectorate has been working overtime.

Note that the four Hornsea wind farms are planned to have at least the following sizes.

  • Hornsea 1 – 1218 MW
  • Hornsea 2 – 1386 MW
  • Hornsea 3 – 2852 MW
  • Hornsea 4 – 2600 MW

These four wind farms give the Hornsea complex, a total capacity of at least 8056 MW.

When I worked at ICI in Runcorn in the late 1960s, I used to cross the Runcorn Bridge twice every day and would see Fiddlers Ferry power station, with its eight cooling towers, on the North Bank of the River Mersey to the East. It was generally thought of as a large coal-fired power station.

These pictures of Fiddlers Ferry power station were taken in 2021, from a Liverpool-bound train on the railway bridge.

This Google Map shows the power station.

Note.

  1. Fiddlers Ferry may have been large for its time at 1989 MW, but it is still less than a quarter of the size of the Hornsea wind farm!
  2. Drax power station in 1986 at 3960 MW, was larger than Fiddlers Ferry, but was still less than half of the size of Hornsea!

Hornsea wind farm is a true green giant!

This paragraph is from the Hornsea Project 4 section of the Wikipedia entry for the Hornsea wind farms.

Construction of the wind farm was provisionally expected to start in 2023, and be operational by 2027, at the earliest. The project’s capacity is unknown by Ørsted due to the ever increasing size of available wind turbines for the project.

When completed, it could be even bigger.

Mersey Tidal Project And Where It Is Up To Now

The title of this post, is the same as that of this article on the Liverpool Echo.

This is the sub-heading.

With a major agreement on the project reached this week, we take a look at what it all means.

There is a section, which is called So What Is A Mersey Tidal Project?, where this is said.

The idea is to build a huge damn structure in the River Mersey with turbines that can harness energy from the tides of the river and convert it into clean power. The city region combined authority is hopeful that this could power up to 1 million homes and create thousands of local jobs

The city region has one of the country’s largest tidal ranges so it is seen as a perfect opportunity to explore a tidal project here. It is hoped such a project could generate a ‘plentiful, reliable supply of clean, green energy for generations to come.

In the 1970s, I did a small project management consultancy at Frederick Snow and Partners in London. They showed me their ambitious plans for a Severn Barrage, which was a tidal scheme, that would have created a tenth of our electricity and would have cost around a billion pounds.

But Harold Wilson, who was Prime Minister at the time, felt that the money would be better spent on building massive coal-fired power stations, rather than building a clean power station, that would last centuries.

A second section is called What Happened This Week?, where this is said.

This week the Liverpool City Region signed an agreement with the company behind the current world’s current largest tidal project with a view to learning lessons.

The Sihwa Lake tidal range power plant, which is operated by Korea Water Resources Corporation, generates 552GWh of clean, green energy every year, replacing the equivalent of 862,000 barrels of oil a year.

Jeong Kyeong Yun, Vice President of Korea Water Resources Corporation, known as K-water, was in Liverpool this week to sign an historic Memorandum of Agreement with Mayor Rotheram. It is hoped the agreement will pave the way for close co-operation between the two tidal power projects, through reciprocal visits and information sharing.

Note.

  1. The Liverpool Echo is still making spelling mistakes, like damn instead of dam. In the 1960s, Fritz Spiegl used to give us all pleasure by writing about them.
  2. 552 GWh would keep the UK powered up for nearly a month.
  3. The Sihwa Lake Tidal Power Station has a comprehensive Wikipedia entry.
  4. The Sihwa dam has a road over the top.
  5. Unlike Frederick Snow’s scheme for the Severn, Sihwa only generates power, on the incoming tide. But it does generate 254 MW.

As ever, Liverpool is thinking big and getting the experience from those, who know what they are doing.

This last paragraph, gives the thoughts of the Mayor.

Mayor Rotheram said that with the right support, he hopes the project could be generating clean, renewable power by the end of this decade.

I would go along with that.

The Mersey Tidal Project And The Mersey Gateway Bridge

Frederick Snow’s plans for the Severn could have incorporated a new road and rail crossing of the estuary.

This Google Map shows the the Sihwa Lake Tidal power station.

The road over the dam is clearly visible.

I took these pictures of the Mersey Estuary as I came back from Liverpool on Tuesday.

This Google Map shows the Mersey Estuary.

Note.

  1. The River Mersey flowing from the North-East corner of the map to the South-West corner.
  2. On the South Bank of the Mersey, there is the deep-water channel of the Manchester Ship Canal.
  3. The bridge in the North-East corner of the map is the Mersey Gateway Bridge.
  4. Then there is the pair of bridges at Runcorn; the Silver Jubilee Bridge and the Runcorn Railway Bridge.

I am fairly sure, that the Mersey Tidal Project would be built downstream of the pair of bridges at Runcorn.

This Google Map shows the Mersey Estuary from the Runcorn Bridges to the mouth of the Manchester Ship Canal.

Note.

  1. The Mersey Gateway Bridge and the two Runcorn bridges are in the North-East corner.
  2. The route of the Manchester Ship Canal is clearly visible.
  3. Liverpool John Lennon Airport is on the North Bank of the Mersey.
  4. The M56 and M53 Motorways run East-West across the map to the South of the River.

This map leads me to the conclusion, that a tidal barrage with a road on top could link Liverpool to the M56.

I have some thoughts.

Rail Access To Liverpool

There is an electrified railway between Liverpool and Ellesmere Port.

  • The railway can be picked out running across the bottom of the map.
  • In Liverpool’s Vision For Rail, I talked about Liverpool City Region’s plan to expand this service to Helsby, Frodsham and Runcorn East.
  • Helsby and Frodsham are shown on the map.

I wouldn’t be surprised to see a new Park-and-Ride station, where the M56 and the railway cross.

Ship Access To Manchester And Other Ports

Barrages usually have to provide access for ships to pass through to any ports behind the barrage.

But the Mersey Tidal Project already has that access. – It was built in the 1893 and is called the Manchester Ship Canal.

There is probably strong protection between the Mersey and the Canal between the mouth of the Canal and Runcorn, which may impact positively on the costs of the barrage.

The Simple Barrage

Sihwa Lake Tidal power station is a simple barrage with a bridge over the power station in the middle.

This Google Map shows the location of the power station.

Note.

  1. Seoul is in the North-East corner of the map.
  2. The Sihwa Lake Tidal power station is marked by the red arrow.

This Google Map shows a close-up of the power station.

Note.

  1. The ten turbines appear to be in the gap.
  2. There appears to be a road on top of the barrage.
  3. The area to the West of the power station is marked as a rest area.
  4. A Moon Observatory is marked.
  5. It has bus stops, showing that it is served by the 123 and 123-1 buses.

It is an impressive structure.

I’m sure that this type of barrage would work over the Mersey.

  • A road could be built on top.
  • It may only be able to generate electricity,from an incoming tide, like Sihwa.
  • It could incorporate a rest area.

I do suspect though Liverpudlians would add a few unique touches of their own. Perhaps some liver birds or superlambananas.

The Frederick Snow Solution

The Severn is a wide river and he proposed that there would be a dam across the river, with a spine running East along the middle of the river.

  • The spine would divide the river into two lakes.
  • On the incoming tide, sluices would open and allow water to flow into the Northern or high lake from the Mersey estuary.
  • On the outgoing tide, sluices would open and allow water to flow out of the Southern or low lake into the Mersey estuary.
  • Water would flow between the high and low lake through turbines to generate electricity.
  • I have assumed that the high lake is on the North side, but if the geography is more suitable, the high and low lakes could be reversed.

In the design for the Severn Barrage, an International airport would have been built on the spine.

But Liverpool already has a nearby International airport, so perhaps it could be much better to install a large electrolyser and hydrogen storage on the spine.

World’s First Offshore Wind Farm Using 16 MW Turbines Enters Construction In China

The title of this post, is the same as that of this article on the offshoreWIND.biz.

This is the sub-heading.

China Three Gorges Corporation (CTG) has started construction of the second phase of its offshore wind farm Zhangpu Liuao. The project will be both China’s and the world’s first wind farm to comprise 16 MW wind turbines.

I hope the Chinese have done all their calculations, research and testing. The dynamics of large wings are tricky and there are a lot of square law factors involved. I’d always be worried that at a particular wind speed a dangerous vibration will be setup.

How many Chinese engineers have seen videos of Galloping Gertie?

As the video says, no one was injured or killed, when the Tacoma Narrows Bridge fell into the river, but we nearly had a very similar disaster in the UK. I used to work at ICI in Runcorn and at the time, I lived in Liverpool, so every day, I went to work I crossed the Silver Jubilee Bridge twice.

One day, after a party in Cheshire, I even got so drunk, I had to stop the car on the bridge and was sick into the Mersey. It was before C and myself were married and she always claimed she nearly called the marriage off, after the incident.

But have you ever wondered, why that bridge is a through arch bridge rather than a suspension bridge as over the Forth, Hmber and Severn, which were all built around the same time?

Wikipedia has a section, which describes the Planning of the bridge.

The new bridge had to allow the passage of shipping along the Manchester Ship Canal. Many ideas were considered, including a new transporter bridge or a swing bridge. These were considered to be impractical and it was decided that the best solution was a high-level bridge upstream from the railway bridge. This would allow the least obstruction to shipping and would also be at the narrowest crossing point. The first plan for a high-level bridge was a truss bridge with three or five spans, giving an 8 yards (7 m) dual carriageway with a cycle track and footpaths. This was abandoned because it was too expensive, and because one of the piers would be too close to the wall of the ship canal. The next idea was for a suspension bridge with a span of 343 yards (314 m) between the main towers with an 8 yards (7 m) single carriageway and a 2-yard (2 m) footpath. However aerodynamic tests on models of the bridge showed that, while the bridge itself would be stable, the presence of the adjacent railway bridge would cause severe oscillation.

The finally accepted design was for a steel through arch bridge with a 10-yard (9 m) single carriageway. The design of the bridge is similar to that of Sydney Harbour Bridge but differs from it in that the side spans are continuous with the main span rather than being separate from them. This design feature was necessary to avoid the problem of oscillation due to the railway bridge. The main span measures 361 yards (330 m) and each side span is 83 yards (76 m).

But that misses out part of the story that I learned about at ICI.

I developed a very simple piece of electronics for ICI Runcorn’s noise and vibration expert. The equipment allowed the signals from two noise meters to be subtracted. This meant that if they were pointed in different directions, the noise generated by an object or piece of equipment could be determined.

The noise and vibration expert had tremendous respect from his fellow engineers, but his involvement in the design of the Runcorn bridge had elevated him to a legend.

The designers of the suspension bridge, that is detailed in the Wikipedia extract, presented their design to the ICI (Merseyside) Scientific Society.

The noise and vibration expert was at the meeting and questioned the design and said it would collapse due to oscillations caused by the presence of the railway bridge. He advised aerodynamic tests should be done on the bridge.

His back of the fag packet calculations were shown by tests to be correct and the bridge was built as a through arch bridge.

These pictures show the bridge.

They were taken from a train on the railway bridge.

Crossing The Mersey

I took these pictures as the train to Liverpool crossed the Mersey yesterday.

Note.

  1. The green bridge is now called the Silver Jubilee Bridge, but when I lived in Liverpool and worked at ICI in Runcorn, everybody called it the Runcorn-Widnes Road Bridge.
  2. The train is on the Ethelfleda, Britannia or Runcorn Railway Bridge depending on your preference. I tend to use Britannia, as the guys I worked with used that name.
  3. The three towers of the cable stayed Mersey Gateway Bridge can be seen in several pictures.
  4. Fiddlers Ferry power station is now decommissioned, but was an almost 2GW coal-fired power station.

In January 2011, I took a video as I crossed the Mersey and it is shown in Train Across the Mersey.

The Future Of Fiddlers Ferry Power Station

The Wikipedia entry for the power station, says this about the future use of the site.

Demolition of the station was due to begin in 2020 and will take up to seven years. The land upon which it sits will be redeveloped, with Warrington Council stating it had designated the land as an employment site.

As it obviously has a high-capacity electricity connection and there is a lot of offshore wind power in Liverpool Bay, I would feel it could be an ideal location for a large battery of perhaps 2 GWh.

The Future Of The Britannia Railway Bridge

The bridge was opened in 1868 and is Grade II* Listed.

Did the designer of the bridge; William Baker ever envisage, that in the future his bridge would be carrying trains over 250 metres long, that were capable of 125 mph?

Probably not! But in a few years, the bridge will be carrying High Speed Two Classic Compatible trains between London and Liverpool.
