GWR Class 165/166 Turbo Diagrams

[800301]

Presumably due to Reading to Wokingham being closed from Saturday to Monday.

Yes, conducted by SWR drivers

Am I remembering correctly that the last time they tried this, I think when Reading to Guildford was shut, GWR messed it up and they ended up having to run replacement buses on the whole line?

166207 is operating 1D58/1N61 today BTM to Oxford and return

This time a VSTP move from Reading to Guildford via Woking. Oddly running as a 5Q rather than the 5Z that it ran as last time.

Its showing as 165127 to Exeter only, so presumably it'll get cancelled there unless they run an 80x down to swap it with.

I'm very late, but did the 165 make it to Plymouth? I don't have RTT+ so can't check.

No, was due to be swapped out for a 150 but nobody told anyone so ended up being cancelled at Exeter with everything sent to the depot

I am not sure if this the right thread but a notable appearance this afternoon, if the allocation is correct, of 165130 which I don't think has seen the outside of St Philips Marsh depot for over a year, if not nearly two years? It looks like a test train, so it does seem plausible.

Thanks for the update. Fingers crossed it is 165130 as I know quite a few (myself included)who are waiting to get the red pens out for this unit

It looks like the test run was OK, because it is in service today

Certainly was in good fettle on its first working this morning (07.04 Bath - Filton) though at least one door button was on strike!

We had a plea to assist in the early hours to provide a spare unit so it could cover west work for a day. It was agreed the spare unit would go out on the back of the Greenford unit to Reading Station where an Exeter driver, who had been deposited on the Up Night Riviera, would come and collect it.

What’s that I hear? “The railway only operates for own convenience and not the convenience of its passengers” yeah Ok

 

[REVUpminster]

What has happened to the 150s. I only count 11 on the usual Devon and Cornwall branches and that's with buses on the Looe and St Ives branches.

At least two were on the mainline

There should be another 4 out somewhere. Requirements is 15/20 and there is only 5 on the Stop list so all 15 should be out.

The Windsor shuttle has failed this morning at Slough. Looks like it will be heading back to Reading. Hopefully they source a replacement unit.

165126 has replaced 121 according to realtimetrains.

 

[43025 Exeter]

I see there are no units showing yesterday (on RTT) for Didcot - Banbury and return workings 2M08, 2V11, 2M16, 2V19, 2M24, 2V27, 2M32, 2V35, 2M40, 2V43, 2M48, 2V51, 2M56, 2V59, 2M64, 2V65, 2M72 and 2V73; think it was something from 165120 and 165126 that was allocated.

For some reason 165126 has been operating incognito since last Thursday, but I think it has been in service every day bar Sunday. It has certainly been on the diagrams that I have eye-balled which have had no allocation on RTT or LRR, including 2V35/2M40 that you reference for yesterday. I have not seen it today, but I assume it is on the diagram commencing with 2M02 that has no allocation. Yesterday, 165120 was parked on the naughty step on Reading TCD.

== Doublepost prevention - post automatically merged: 29 Jan 2026 ==

Whatever the issue was with 165126, it now shows up on RTT (Thursday) and so do all of its workings for the past week

More Windsor shuttle problems today with the unusual sighting of two turbos in the bay at Slough. The unit at the buffers was being checked over by staff whilst a second was providing the service. I would be interested to hear what signalling arrangements had to be carried out to allow that.

 

[MasterPhillips]

The unit failed yesterday, the last Windsor shuttle train last night was supposed to be cancelled to have time for the failed unit to leave the station but sounds like that plan didn’t happen if the unit is still there.

None because you can be permissively worked in Slough, as the above poster has said, it should have be rescued last night by using the last unit but I assume bigger problems were found

 

[CR165022]

It would seem that the unit working the shuttle today had to take the failed unit it with it back to Reading before coming back by itself, resulting in the few cancellations today.

All the interesting things seem to happen in half term!

As if to prove my point, it's not working today, so I'm waiting for a bus - fortunately I am for once not under time pressure.

I only encountered one delayed service on the branch last year...

It was reported as a points failure so the turbo is likely not to blame. No 8 bus should be every half hour.

RTT says that it was "a failure of the on-board safety systems". I saw it shunt out of the station at 14.25 but didn't get the number. The board at Central station claimed that the 16.20 was running, so I thought I'd take that rather than chance the bus, but it has since revised that to the 16.40. Oh well...

 

[CR165022]

Does seem like it was a fault with the unit. It was showing as 165124 this morning until the cancellations but is now showing as 165123 for the rest of the day.

It is 165123, I've just escaped onto it from a thunderstorm...

The points failure at Maidenhead meant a replacement unit could not be sent to Slough for a while
