Not sure where you are getting your figures from, but if you add up the number of bi-modes in class 800, 802, 805 and 810 there are 186 bi-mode trains. Of that 138 are five car bi-modes. That gives us 48 9 car class 80x bi-mode trains as you state. There is nowhere near the number of 202 bi-mode trains that you state above.
I thought I explained how I got to the total of
potentially 202 AT-300 bi-modes above? Ie. there are enough diesel gensets under the nominally 'electric' class 801 units to create either 10 or 16 additional bi-modes (depending on whether the 9-car class 801s have one genset or two) without building any more just by moving gensets between units. As you state, the current total is 186 bi-modes - use the gensets out of the 801s to make bi-modes and you could do:
- 186 + 10 = 196 bi-modes or
- 186 + 16 = 202 bi-modes (this is why I said potentially 202 rather than currently)
I suspect that you maybe including the class 801, whilst yes having a single diesel power unit for recovery are actually counted as being full electric units, the same as class 803 units and will be the case with the class 807 units.
Do the class 803s and 807s have a diesel power unit for recovery? I thought it was only the class 801s that did, with the 803s having batteries instead.
Even with the best electrification work strategy, it will be years until Network Rail get round to wiring up the Durham Coast, by which time the 180s would have probably all fallen to pieces.
Yes, the Durham Coast line is a way down the list but there are plenty of other places which aren't. For example, Hull could be fairly high up the list which would free up the Hull Trains 802s (and maybe some of TPE's 802s) for a cascade to Grand Central. Since GC has a larger fleet than Hull Trains, diesel gensets out of 801s could be used to make up the numbers.
Yes that was a plan for a few 3 car 331’s for Windermere originally (4th car with batteries underneath).
Other than the pantograph well, do you know if there are any differences between the class 195 and class 331 bodyshells?
To be honest, but for the seats (which are too hard for London - Leeds, let alone London - Inverness) I'm not fussed about the rest of it.
Yes, the current AT-300 series units have awful seats (I think the longest I've done on one is Carmarthen to Cardiff, and the seats were too hard for that journey in my view let alone anything further). That is something that needs addressing in future (any new AT-300 classes, rather than additional 803s/807s etc., should also have plug doors in my opinion).
