SWR "Planned Cancellations"

markle · 18 Jun 2026

SWR has a whole bunch of "planned cancellations" this evening, which means:

- Chessington gets 1 train an hour
- Guildford via Chobham gets 1 tph
- Weybridge stoppers get 1 tph
- Windsor gets 1 tph

Station staff can't explain why. Cancelled services aren't listed on any departure boards as "cancelled"; they just aren't shown. I don't recall seeing any warnings about frequencies being reduced.

What's going on? The comms here is dismal.

I imagine it's related to Royal Ascot - and they're PD cancellations so they are a planned cancellation in the sense that they've not been in the timetable at all (and journey planners) since around mid-May by the looks of it.

markle · 18 Jun 2026

Regular commuters don't check the journey planner for each daily commute - they know the service patterns.

It's a bit poor to just "disappear" commuter services with no comms or warning.

At least for weekend engineering work we get a warning.

Quite correct, it does not. My apologies.
My sight reading at geography is not what it used to be!

Especially for the midweek trains, where regular passengers rarely check journey planners, surely SWR putting a note on the guards schedule cards for the week prior saying, make and announcement about the planned cancellation of this train next week, would be the best option

devon_belle · 20 Jun 2026

Given SWR flood our eyes and ears with plenty of superfluous announcements, it's frustrating that they wouldn't give better comms for changes to the regular timetable that might catch out regular customers.

I doubt this would even be permissible, in that format.

Train crew can only really be asked to do something like that, and not made to, certainly.

Certainly the better approach.
Announcement/ notices at stations.

Which may have already been undertaken.
But we all know how deaf / blind the general commuter is to extraneous information being bombarded in their direction are these days.

Yes, but as discussed elsewhere can you blame them? The announcements are excessive, and posters are usually just generic ones for the whole network which may not catch their attention.

I can't, no.
I also don't know what's been enacted in this case in terms of comms. It does feel, though, a little disconnected.

But I do feel in general that people do need to take better responsibility in maintaining their gerneral awareness of their surroundings.
Not applicable here, I should add, for the day of travel, but there's the possibility advanced notice was given and just wasn't heard.

devon_belle · 20 Jun 2026

Southern use the third line of the dot matrix displays to give info on planned engineering works on routes it is relevant to. Do SWR do the same? I find this is helpful, but I'm slightly more aware than the average commuter.

I agree with this.

There are varying solutions employed by the different operators.
They use the same spaces available (on screen / departure boards and audio outputs) in different ways.

I've seen talk of LNER using departure board space for luggage storage info.
Chiltern have departure board space for Wemebley and other events / planned disruption.
Southeastern, too, I've seen and heard in various ways also.
I think avanti also employ audio announcements for other purposes.
And as you describe ld southern take a similar approach.

If only there was some form of national approach to the railways and it's systems...

All SWR staff should have access to internal information regarding planned service changes for the week ahead. The issue will be that lots of those on the frontline will ignore the email or message and therefore know nothing about it and be stumped when asked by passengers. How you make more staff aware I'm not really sure though.

I don't recall having seen or heard that on trains (though I might have tuned them out), but on SWR stations they do have both audio and departure board warnings of forthcoming engineering works, usually playing for a few days beforehand. For major works (notably the several 9-day half term closures for resignalling on the Direct), banner posters were attached to platform fences some weeks beforehand.

norbitonflyer · 20 Jun 2026

They also do this every time there's a rugby match at Twickenham - diverting Shepperton services that way, and consequently halving the service at Kingston. Yhey never give any prior notice, unlike closures for maintenance work.

Did the diversions for Royal Ascot or Twickenham also happen before COVID? Or was it purely extra trains, without existing services diverted?

davews · 21 Jun 2026

But it didn't work very well on Thursday:

Attendees at the Royal Ascot yesterday were stuck on a train back to Reading after a car towing a horsebox collided with a bridge.

https://www.bracknellnews.co.uk/news/26209999.reading-trains-delayed-horsebox-collided-bridge/

The irony of a horsebox striking the Broad Lane bridge!

That doesn't look like a towed horsebox - more like a lorry-type one.
It looks like it would have made it if it had stayed within the white "goalposts" painted on the bridge.
I note what looks like an Irish registration plate. Foreign vehicles sometimes hit bridges because the driver is unfamiliar with Imperial measures, but in this case the bridge is marked in both metric and Imperial.

In the Good Old Days, the horses would have travelled by rail.

I see today there are loads of SWR cancellations due to the 'forecast severe temperature'. For instance they have removed one whole diagram on the Reading service. Although shown on journey check as 'cancelled' they just don't show in the schedules at least as seen on RTT, they have just been removed.

From the list of cancellations on journeycheck it looks to be an approx 25% reduction in the number of diagrams across the board for Metro & Windsor line services. So the removal of one of five 2*458/4 diagram and the removal of 12 of 48 701 diagrams. The cancelled trains do show up on LRR as cancelled, they are just missing from RTT.

They are not missing - they are under the CAN filter. Because they come under scheduled cancels banner rather than on the day due to when and how they were cancelled.

But they are VCN cancellations and not CAN. For example 2C15

Realtime Trains | 2C15 0748 London Waterloo to Reading | 23/06/2026

Real-time train running information for 2C15 0748 departure from London Waterloo to Reading on 23/06/2026. From Realtime Trains, an independent source of train running info for Great Britain.

which LRR shows as cancelled at 0549 which as a layman I would have thought of as on the day cancellation. Obviously I am missing out on the subtleties of how cancellations are described, so I do not have the full picture.

Tom · 23 Jun 2026

A VSTP CAN (VCN) is still a CAN.

These are what is known in the industry as the notorious 'P codes' (PG) as opposed to PD codes which are the usual done-in-timetable-long-before. They can use P codes as long as they are agreed before 10pm the day before operation (hence the Planned Timetable of the Day thing in NRCoT for a while)

That particular train would have been cancelled on call (hence 0549 you see the message, almost exactly 2 hours ahead). The cancellation would have been done via the VSTP process - hence why RTT will have hidden it at the point at receiving that bit. The cancellation message would have been on call, but it was cancelled long before.

Edit: actually that's an hour before - as we're in a different timezone. The train was called at 0648 local, so was cancelled at 0649.

Thank you. I did wonder if this was as a result of P coding but the 0549 time stamp is what threw me. Thank you for explaining

Looks like the driver did stay within those markings to my eye, as they appear to line up with the kerbs which form a narrower passage on the road surface, the camera angle making this less obvious. If the image had been taken from directly behind the wagon, one could gauge it more accurately. It does however look like the front drivers side of the bodywork is rising up - horse(s) standing at the rear tipping the front end by just enough to make a difference, or just a result of the vehicle body jamming under the arch and the driver still having their foot on the loud pedal?

Was reliably informed yesterday of pre planned cancellations in the New Forest area first thing this morning due to (quote) 'Adverse weather' predicted. How true I know not, not having delved any further in to same?

The Bournemouth to Winchester stopper is not running today.

Robert Carroll · 25 Jun 2026

On Wednesday evening, the down main slow was closed from Waterloo to beyond Wimbledon and everything was using the down main fast. The up main slow was still in use as far as the West Crossings. So, it seems that an issue with the track on the down slow is the root cause of the severe reduction in services. What was left was running very late too.
