One thing I've always wondered is if 350s got cleared for the Core section of the Thameslink route, would they have the same problems with switching from AC to DC at Farringdon and also the same problems with the doors at St Pancras?
i can answer some off this, with the doors on the 350's these are operated the same as on a 319 the driver/guard has full control over them(no stupid gps required), so no there would be no door trouble at all.
im not sure how the ac/dc change over happens on a desiro, but i believe the shoes stay down all the time on a 350, where as on a 377 they retract into a stowed position, so there would be no problem going ac/dc.
The main problem with the 377 change over was that there was too much juice in the 3rd rail and the mitrac on a 377 just said no and would retract the shoes, so there was no option but to go back on ac and escape to moorgate, this seems to have now been sorted out and there are 99% less failures at farringdon southbound.
Hope that helps.
