Any idea what is going on today (15th September)? At least two 2 carriage diagrams out on the North Downs line.

Only 1 short form on N Downs, the timetabled 2 car is a 2 car as planned.

As to why, it’s just a Turbo misbalance, appears Oxford had 4x 2 car and 1x 3 car overnight; rather than 5x 2 car. That leaves Reading short of a 3 car to send out in the morning, and a 2 car over.

Controller and Depot will have worked together to identify which diagram to run short, taking in a plethora of factors and arrived at that diagram being the least-worst option.

Right, thanks! Didn't actually realise there was a regular 2 carriage north downs diagram.

Where is there now a 3-car diagram elsewhere on the LTV network to lead to a 2-car diagram on the North Downs? My recollection was that the 9 2-car diagrams for 10 units were Greenford, Windsor, Marlow, Bedwyn and 5 on the Oxford locals.

Which is the 2-car diagram on the North Downs, noting that I have just ridden 165120 on the 0820 Reading to Redhill so that could be it.

How many 3-car Turbo diagrams off Reading are there now?

The Newbury - Bedwyn IET replacement shuttle eats up your extra N Downs 3 car. With the corresponding timetable reduction it makes more sense to 2v3 1x round trip in the morning on the N Downs (1O55/1V39), than all day 2v5 the Bedwyn.

Current weekday diagram totals for the East Fleet:-

8x 2 car
14x 3 car

10x HEx 387
33x Classic 387
4x GX 387
2x c2c 387

Classic/GX 387s are completely interchangeable so the diagrams are indicative of what’s extra services only; not that a GX/Classic unit will be used - but that’s OT for this thread.

The IET situation has muddied the waters somewhat for the time being, your post is correct for the medium term aspiration.

Speaking to a driver and 166213 is the only one he can get up to 90mph.
In Devon? The only place you can anyway is Exminster straight and most 158's don't get to 90 before having to brake for the speed reduction in each direction

That’s like the old joke about Penzance HST drivers, it just meant they had a train that got to 65mph slightly quicker than the other stock they drove :lol:

Expecting the three 166s on 2F10, 2F11, 2F12 today and they were 166211, 166219 but on 2F12 was 158798 and it was three cars!! The database often mentioned here has it as a two cars. Luckily although probably planned it was not on the school run.158798 at Paignton 0915am 19 October 2021.JPG

158798 has always been a true 3 Car from birth and part of a batch which went initially to Trans Pennine Express,

Believe it came down from Bristol Temple Meads on 2F05 this morning vice 166.

A bit late now, but on Sunday as I was heading for Cardiff I saw 166 201 (quick look, correct me if I'm wrong) at Exeter St Davids on 15.19 to Barnstaple. Do these units often go up there?

166201 and 166219 were both on Barnstaple on Sunday.
Its annoying as we keep asking that the diagram that involves 2R81(07:22 from Barny) be made a 166 on a daily basis due to the extra capacity that a 166 has over a 158/9 both in terms of seats and standing room yet a flat refusal from train planning!

Seems the only logical answer unless a 4 car 150 can be found as a 4 car 158 would lose too much time on the short platforms.

how much would time and money would it cost to retrofit the same SDO system that SWR use to GWRs sprinter fleet?

I suppose the use of 158s to Barnstaple is the perceived dwell times at intermediate station is not very long because not many passengers getting on and off at the same time.

More 166s will depend on 769s which GWR seems to be having problems with. 19 of them which, I always get shot down for on this site, will cascade 165s west eventually ousting the 20 150s. It's why all the money of GWR, not government, was spent on Exeter depot.

Bristol like all the others with a few out stabled at Exeter. Let's not forget that from May there will need to be two Okehampton diagrams and we're yet to know what the demand for these will be.

Whilst its getting into the realms of being speculative though relevant to the thread, should Wellington and Cullompton get the all clear the current Cardiff-Taunton workings will be extended to Exeter/Plymouth/Penzance to accommodate this, yet more diagrams possibly for turbo's

Exeter cannot hold the 150s it already has let alone more 166s unless something goes.

Regarding extended Taunton workings extended to Exeter; this is on the cards as platform 2 is extended. GWR supposed to have the money for it according to Modern Railways in July. Most of the staff have vacated the portacabins to the new depot accommodation. This would pave the wave for future trains (Devon Metro) serving Wellington and Cullompton to reverse at Taunton.

Exeter holds the 150's easily, most are out on the Cornish branches anyway.
I'm one of the staff moved over to the new depot so I do know what goes on, the portacabins still very much in use for other depot and TOC traincrew taking their breaks, only Exeter based crews are allowed to use the mess facilities in the new depot at this time, the 166s are mostly stabled around the back of the new depot.

They’re not permitted to be booked on 2BXX/2RXX as their wheelchair spaces don’t line up with the Harrington Humps at various stops. Short term stand ins only

Thanks for that, at least some logic behind it.

Stock numbers are now appearing on Realtime trainss. Will not have to keep going to see what train it is.

Ticket Inspector at Torre used his mobile phone and an app to tell me where the two trains were that I hadn't seen. One was the next into Torre and the other was working Bristol area.

Seen all 21 bar 166204.

That's very useful. I believe that any Turbo that basically says Coach A, B and C is a 166 and D and E of course a 165.
