Silicon Roundabout – 28th August 2021
The big push started today to open the new entrance to Old Street Station in Cowper Street.
According to this page on the TfL web site, which is entitled, Old Street Roundabout, these changes will happen on the 31st August 2021.
- The new entrance at Cowper Street will open and will provide direct access for customers to the station.
- Subway 1 (northeast exit) will be permanently closed. Subway 3 (southwest exit) will remain open
- The staircase at Subway 4 (northwest exit), will re-open and the ramp at Subway 4 will permanently close. The green line leading to Moorfields Eye Hospital will be reinstated along the stairs
I took these pictures from a 21 bus, this morning.
Note.
- The first four pictures show the North-West exit, which is Subway 4.
- The sides of the steps at Subway 4 seem just to need application ofsurface finish and handrails.
- In the last picture, it looks like the contractors are getting ready to resurface the South-East corner.
I also took this picture of the Cowper Street entrance yesterday.
The entrance looks to be not far from finished behind the hoarding.
If I get a chance, I’ll go back and have a look sometime in the weekend.
Southall Station – 28th August 2021
Southall station is now another station, that is ready for Elizabeth!
I took these pictures this morning.
Note.
- It appears all four current platforms will be getting step-free access with lifts.
- The leg of the bridge to Platform 1 hasn’t been completed, although the lift tower is in place.
- The station signage is bi-lingual; English and Punjabi.
- A new modern station building has been added to the North of the original station building, which opened in 1839.
- A level walkway runs between the new station building and the footbridge.
This Google Map shows the station.
Note.
- This image was taken during building of the footbridge.
- The new station building and the walkway to the footbridge don’t appear to have been erected at the time of the image.
- The Southern pair of lines are the fast lines that go through Platforms 1 and 2.
- The Northern pair of lines are the slow lines that go through Platforms 3 and 4, which will be used by Crossrail.
- There is a fifth unused platform face, that shares the island and the stairs and future lift with Platform 1.
This map from cartometro.com shows the lines through the station in detail.
Note the single line coming in from the South-East is the freight-only Brentford Branch.
A Passenger Service On The Brentford Branch
It would appear that, when the builders complete the step-free footbridge at Southall station, that there will be a step-free interchange between Crossrail and any future passenger service on the Brentford Branch.
I feel that the Brentford Branch would be ideal for one of Adrian Shooter‘s Pop-Up-Metros, that would use Vivarail‘s Class 230 trains or similar.
In its simplest form a train would just shuttle between Brentford and the unnumbered fifth platform at Southall station.
Could British Land’s Plans For Finsbury Square Car Park Include A Rail Link To The Northern City Line?
This map from cartometro.com shows the railway lines in the area of Liverpool Street, Moorgate and Old Street stations.
Note.
- The four tracks in black are the Northern and Northern City Lines.
- It is planned to install digital signalling on the Northern City Line to increase capacity.
Finsbury Square is to the East of these lines.
The Northern Line is about fifteen metres deeper and underneath the Northern City Line.
This picture shows the escalator between the two lines at Moorgate station.
I wouldn’t be surprised to find that the Northern City Lines are deep enough to be below the Finsbury Square Car Park.
So would it be possible to run a four-car electric multiple unit into the Finsbury Square Car Park, so that there is no need to shuttle parcels and light freight to Liverpool Street station.
The digital signalling on the Northern City Line will probably allow a few extra trains to travel to a siding in or under the Finsbury Square Car Park, so it wouldn’t effect services into Moorgate.
Between Liverpool Street And Wimbledon Park Stations
This morning, after I’d finished walking to Liverpool Street station, I took the new route to Wimbledon Park station.
- Liverpool Street to Whitechapel on the Hammersmith & City Line.
- Whitechapel to Wimbledon Park on a District Line train.
The change at Whitechapel was just a walk across the wide platform.
I have rarely gone between Whitechapel and Wimbledon on the District Line and this was one of the first times since the 4LM (Four Lines Modernisation) project has been well under way.
The difference showed in the station dwell times, with only four stops taking more than thirty seconds from brakes on to brakes off.
- Victoria, Sloane Square and South Kensington still took under a minute.
- But Earl’s Court took a lengthy six minutes.
This map from cartometro.com shows the stations.
Note.
- The stations are all close together.
- There are some complicated junctions.
- The District Line splits into two to the West of Earl’s Court station.
This section will be challenging to any signalling system.
It works out that the average dwell time between Whitechapel and Wimbledon is around fifty seconds.
Walking From Finsbury Square To Liverpool Street Station
In Finsbury Square Car Park Becomes British Land Hub For Delivery Drivers, I wondered if
.
So today, I walked the route from Finsbury Square To Liverpool Street Station.
Note.
- The roads around Finsbury Square are probably the narrowest on the route between Finsbury Square and Liverpool Street station.
- Sun Street, Appold Street and Primrose Street are wide roads and didn’t strike me as too busy for eleven in the morning.
- The Old Cab Road is a high capacity route into Liverpool Street station between Platforms 10 and 11.
If Finsbury Square Car Park is be used to distribute parcels and light freight that is to be handled in Liverpool Street station, the roads between the car park and the station are more than adequate for an electric shuttle truck designed for the task.
But
- I suspect that Finsbury Square Car Park would need remodelled access ramps.
- There might be a need for a second entrance or exit on the East side of the site.
- The gardens on top probably need a makeover.
I wouldn’t be surprised if British Land dug another floor or two beneath the car park.
Wimbledon Park Station – 27th August 2021
Wimbledon Park station has now gone step-free so I went to have a look.
Note how the lift has been squeezed in neatly alongside the staircase.
I suspect this lift layout can be copied at a lot of stations.
Finsbury Square Car Park Becomes British Land Hub For Delivery Drivers
The title of this post, is the same as that of this article on The Times.
It is a surprising headline or is it a logical development given some of the projects in the rail freight business.
In A Freight Shuttle For Liverpool Street Station Planned. I talked about Rail Operations Group and their plans to run a freight shuttle between London Gateway and Liverpool Street station.
- Trains will be Class 769 bi-mode trains.
- The trains will be fitted with roller doors, roller cages and strengthened floors.
- Three services will leave Thames Gateway at 0029, 1208 and 1856.
- They will return from Liverpool Street at 0242, 1421 and 2100.
- Services will use Platforms 9 and 10 in Liverpool Street station.
- Goods would be delivered to the customer by e-bikes or electric vans.
This a very detailed plan.
But would it be better, if it had a logistics hub close to or even in the station?
These pictures show the Old Cab Road at Liverpool Street station.
This would probably be the only area in the station, that can be used. But it is not very large. Although it does have an access road at the back of the station.
This Google Map shows the area between Finsbury Square and Liverpool Street station.
Note.
- Finsbury Square is in the North West corner of the map.
- Liverpool Street station is in the South East corner of the map.
- There is an entrance to the Old Cab Road Liverpool Street station on Primrose Street.
- Amazon UK’s corporate office is in the North East corner of the msp.
Could roller cages be rolled into electric vans and taken to Finsbury Square for sorting and onward distribution?
- The car park has a height limit of 1.98 metres.
- It has 258 parking spaces.
- Could it be expanded downwards?
- How many e-bikes would it hold?
It think that this could be the reason for the purchase.
But I would be very surprised if a siding was dug that connected to the nearby Northern City Line that runs into Moorgate station.
Alstom’s Coradia iLint Hydrogen Train Makes Its Swedish Debut
The title of this post, is the same as that of this article on Global Railway Review.
This picture shows a hydrogen-powered Alstom Coradia iLint train near Hamburg
If you’re ever in Hamburg, take a ride to Buxtehude and take a ride to Cuxhaven.
These trains are now in service in Germany and have been ordered in quantity in Germany and have been demonstrated in Austria, Italy and The Netherlands.
The Diagnosis Of My Gallstones
I arrived at Homerton hospital as instructed today for the endoscopy.
Strangely, it was C’s birthday.
The procedure would involve passing an ultrasound probe down my throat and through my stomach to take an ultrasound image of the lump close to my liver.
I’d had two endoscopies before in the late 1990s at Addenbrookes to check for coeliac disease. One was a normal one, but in the second, I was also providing a sample of fluid for a research project at Cambridge University.
I seem to remember at Addenbrookes, I had been instructed to turn up in something like a tee-shirt and shorts, which is what I did. In this case, I took my shirt off and put a hospital gown over my cord trousers.
As I’d had the two endoscopies at Addenbrookes without a sedative, I suggested strongly, that they do the investigation without one this time as well.
The doctor, who was of an age to be very experienced, said he was up for it and we went for it without a sedative.
There was two big differences to the procedure at Addenbrookes.
- There were more staff, than Addenbrooke’s doctor and a technician.
- They were fully gowned up, as opposed to normal clothes.
But, then I got the expression at Addenbrooke’s they were aiming for speed and they were only confirming their earlier diagnosis of coeliac disease. that had been made by a genetic test.
Everything this time, went without a hitch.
- I was laying on my left side.
- I had oxygen tubes up my nose.
- With my right hand I can feel the probe in my stomach.
- To calm me down, a nurse was stroking my beard.
After not a long time, everything was done and I was walked back to recovery area.
Within half an hour, I was informed by the second doctor, that I had got gallstones and they would be taken out by endoscopy on September the 30th. Later they will take out my gall bladder by surgery.
I got the impression, it was the first time, that he’d seen this procedure without a sedative, as he described me as the Star-Of-The-Day. But then I’m a London Mongrel, with more survival genes than a garden full of Japanese knotweed.
I went home the way I came – On the bus!
After Effects
The only after effects were that the air in the theatre had dried me out and my left left arm hurt because I’d been lying on it.
So I vowed to drink a lot of fluids before the operation and do something to improve the strength of my damaged left arm.
Dwell Time On High Speed Two Trains
This document on the Government web site is the Train Technical Specification for High Speed Two trains.
There is a Section 7.15.6, which is entitled Dwell Time
This is said.
The Unit shall deliver 95% confidence of achieving a Dwell Time of 2 minutes at intermediate stations, calculated in accordance with the Static Dwell Time Model in Appendix I using the 1SL.
The rationale is also given.
Achievement of a two-minute Dwell Time is key to achievement of HS2 railway capacity and journey times.
The Static Dwell Time Model evaluates the key architectural elements of the interior layout that impact the Passenger exchange part of Dwell Time.
Dwell time is mentioned many times in the Technical Specification.
There is a Section 9.7.3.4, which is entitled Train Captain Changeover Time
This is said.
The Unit shall facilitate a changeover of Train Captains within a two-minute Dwell Time.
In this time period there shall be time for the exiting Train Captain to:
-
- Release and opening doors.
- Log out of the Cab
- Exit the Cab and Unit.
In this time period there shall be time for the entering Train Captain to:
-
- Enter the Unit and Cab
- Log in to the Cab
- Adjust Cab setting to the Train Captain’s personal preferences
- Fulfil the Train Captain’s role in closing doors, which does not include checking the PTI.
Note how all these actions must be performed in a two-minute dwell time.
The Technical Specification is certainly very detailed.
