Acton Mainline

[flashgordon]

there appears to be a lack of trains stopping at this station now. I gather the locals who use the service are asking for more stop trains there. What is odd the only trains ( t the moment ) thta stop there are the Reading trains and not the Shenfiled trains does anyone know why ??? One in three strains stop there they operator has promised more especially at peak times

Is this the short term changes because of the power issues?

Paddington-Reading blocked due to OLE isolation and lineside fire (5/9)

Will they be pan up anywhere? Or is it just simpler to cancel electric working route wide. Reading

Yes. The service has been heavily slashed so alternative stopping patterns are in place, prioritising peak direction flows. Other stations have also had heavy reductions in service this afternoon, including ones with typically heavier flows, so it’s far from just AML that’s suffering.

The usual service pattern for AML is 4tph (evenly spaced), plus extras during the peaks. The latter were added specifically because peak-time usage was quite a bit higher than originally forecast but came at the cost of slowing down the semi-fasts that were mainly designed for Burnham, Slough and West Drayton, so as always it’s a trade-off.

Shenfield trains have never stopped at Acton Main Line as they are semi-fast.

The standard service is 4tph (all stops to Abbey Wood / Heathrow Terminal 4) with a few additonal peak extras. This week has been disrupted as a result of the aformentioned OLE power supply issues. You are incorrect in that only Reading trains stops there as the majority do not.

The passenger numbers at Acton Main Line have absolutely skyrocketed (+500% I think in last few years) as a combination of a) huge housing growth in the area and b) the Elizabeth line through-running ton Central London in 2023 meaning people are moving away from the Central Line at nearby North / West Acton.

There are indeed clamours to stop more trains, but the same issue occurs at West Ealing and Southall and frankly there is only so much capacity on both the track and trains. It may change in 2027, but not guaranteed. Also this all needs to be put in perspective; in the not too distant past there was no Sunday service and the daily M-F pattern was I think 2tph formed of GWR turbos!

One wonders what is to be done with the 10 additional Liz Line trains now being delivered if, at the pinch points, there is no scope for additional service.

Aren't the extra 10 intended for the extension of Paddington reversers to Old Oak Common (whenever that opens...).

Not on the GWML right now. But there will be additional Abbey Wood to Paddington services. And also extension to Old Oak Common when it opens which is a couple more diagrams. Off-topic but I do worry about how that works without the CBTC extension...

Is Acton Main Line station more-or-less only served by Elizabeth Line trains, running mostly to Heathrow Terminal 4 and to Abbey Wood? (With a small handful running to Heathrow Terminal 5 or to Hayes & Harlington or to London Paddington or to Shenfield)?

Yes it’s a regular Abbey Wood - Heathrow T4 service all day, with the AM peak receiving additional calls from some T5 - Shenfield and Reading - Abbey Wood services.

No current Hayes terminators, that I recall. There is the bay, and it was planned way back, but not currently. Veruy curious to see Acton ML in future ORR figures as the amount of development continues massively, especially north of the station and around the A40.

My understanding was that CBTC was never planned to go beyond Westbourne park onto the GWML, it was always meant to transition to ETCS. There was a NR slide deck available showing the transition arrangement on the connecting lines with a google search at one point but it appears to have dropped off (or I've not searched for quite the same phrase). ETCS was not fitted between Acton ML and Paddington due to the need to redo it all (multiple time) while OOC was rebuilt, even though lots of the approvals were given. I presume it is intended to fit ETCS to the remaining section into Paddington once OOC is complete.

Just the one, late evening, at 2342 (SuX)?

For more services through the core, terminating from the east at Paddington / Old Oak, when operational (long term picture).

Short term theyll cover for the refurb and heavy maintenance.

Yes, accurate. The limit of usable CBTC is the self contained core (including the Westbourne park turn back facilities).

Was there discussion of the potential for some extra West Drayton terminators to deal with the growth on the west side using some of the extra units?

Possibly doable as peak only or substituting a Heathrow to divert to West Drayton.

The paths west of Paddington simply do not provide for any more services at a regular interval.

Plus many, many examples of turnbacks during disruption, which is where the major benefit of the Hayes bay kicks in. That was probably its main original aim tbh. The fifth platform at WD (effectively on the freight line) is similarly also used for alternative turnbacks when the Heathrow tunnel is closed.

Yes it will be ETCS - already an overlay from Ealing towards Heathrow. But there appears to be no timeframe on that last stretch as you say.

All possible from a terminus point of view - although West Drayton P5 does have a not unsubstantial freight usage to/from Colnbrook - and that is not the problem. The issue is the Paddington - Hayes section being completely at capacity on the relief lines.
