That’s correct. It’s mathematically possible to reverse 24tph in that way but it is a performance risk.

Mathematically yes, but you'd probably have departure / arrival conflicts from the 2 running lines, so there would definitely be delays.

No reversing 24tph at Westbourne Park can be planned conflict free, but of course needs everything to run on time. Only one train in five is a conflict if you are using all five roads, everything else can be planned as parallel moves.

Only platform lengthening is mentioned on the Southall page on the Crossrail website.

TfL Press Release regarding opening of Southall ticket hall for Elizabeth line

New spacious station building opens following major redevelopment by Network Rail with more room for customers to enter and leave the station

Southall station has been given a new lease of life by Network Rail with a new ticket hall and lifts opening for customers today (Thursday 26 August) as part of upgrades for the transformational Elizabeth line.

People using Southall station will benefit from a brighter, more spacious station entrance with a new ticket hall constructed from glass and steel, including a wider gateline for tickets and contactless payments. There are also three new lifts and a new footbridge, which provide step-free access to all four platforms at the station.

I love that they have retained the Punjabi (?) signage - I was worried that was going to disappear once the station had been TfL'd.
I wonder whether they will retain it on the platform signage too - not sure where it would go on the roundel...

I do like the retention of the Punjabi signage, and including it on the main entrance.

Mark Wild's latest report to the London Assembly Transport Committee is now available on the TfL website.


It reports the failure of two transformers which is worrying. Are there more of these that will need to be replaced?

On 21 July and 3 August, failures occurred to two Voltage Transformers, which measure the voltage
on the 25kV line. Whilst no injuries were reported, the Office of Rail and Road have been informed of
these incidents. A formal investigation is underway to ascertain remedial action.

There is a plan to demonstrate that the system can cope with 24tph, but it has not been linked in the report to the rollout of the ELR100 software release.

The ELR100 software is the last major configuration before revenue service and is pivotal to the
programme advancing through to the next phase of the programme, known as Trial Operations.

In order to help demonstrate that the Elizabeth line can run at the necessary performance
levels for future service, we will be undertaking ‘testing’ 24tph train movements on the railway in the
autumn. This will be the service frequency in the central section when the full end-to-end Elizabeth
line is operational.

One other issue mentioned is the need to upgrade the Tunnel Ventilation System. Does anyone know what the issues with this are?

Once the software is ready to be commissioned a further blockade, planned for the autumn, will take place
to complete elements of outstanding works in the tunnels, including completion of the Tunnel
Ventilation System (TVS) upgrade works.

TfL have published a new schedule of upcoming engineering work dated 1st September.

Covers TfL rail, overground and Underground and goes through to early March, so dates of upcoming work on TfL rail lines are on the link.

I can add that Sunday's work covers the GEML right up to Marks Tey & Billericay. IIRC this is track work east of Shenfield, and traction power upgrade works (IIRC the AT goes live between Pudding Mill Lane & Shenfield) which mean an all-day isolation of the eastern arm of TfL Rail.

Covid 19 related changes?
There have been design and installation "issues" and "problems" for years. (not enough parallel inter-dependencies from memory, e.g. too many single points of failure)
Ventilation system functionality is linked to the number trains that can run for fire safety reasons, you lose too many fans and the service levels need to drop immediately which is done via the signalling system.

There is also the possibility that the system doesn't work as well in practice as in theory, once the dynamic effects of moving trains are added. That is entirely speculation on my part though

I wonder what will happen to the old Southall station entrance?

The planning application says it and the existing stairs and footbridge are retained for emergency escape. Same as at one of the others, Acton Mainline or West Ealing IIRC, we discussed it in another thread about the Western stations few months ago.

Oh right. I thought it might have been covid related because the news over the last few weeks and months is suggesting that good ventilation is way to reduce the spread of covid.

Anyone know if the second staircase has been descoped from Hayes and Harlington( the one by tescos) the handrail where it would go looks like a permanent edition

The new entrance has opened at Hayes. The wall on platform 5 without cladding appears to be a graffiti target and the roof in the new station building looks poor.with exposed cabling and no tiling where the lights are so don't know how.much work is going to be done.

The full press release is here: https://www.crossrail.co.uk/news/ar...-step-free-access-to-hayes-harlington-station

If it's anything like Ealing Broadway and Southall, there will still be plenty of 'snagging' work going on in the next few months.#

I did also like this slid in at the bottom
London will ultimately fund the majority of the cost of the Elizabeth line, and when the railway opens in the first half of 2022, it will operate as three separate railways. Customers from Hayes & Harlington will initially have to change at Paddington for services into the central section of the route.

A new video today giving details of an exercise in how a situation of a broken rail might be handled.

Today is the first day of testing the auto reverse system in Westbourne Park sidings / back to Paddington. The trials are running between around 0900 and 1530 so will be interesting to see how it all works.

Does it work? Everything seems to be running a bit later than planned.

How does it work in practice then; driver leaves Paddington, gets out of the cab and moves to the other end whilst the train is on the move to Westbourne Park, and then drives off back to Paddington at the other end once its stationary at the sidings? That's what my understanding of it was.

I'm surprised this was signed off from a safety perspective. Westbourne Park sidings is above ground and is not exactly trespass proof
