I was reading in Modern Railways today about that Wabtec Mk3 refurbishing. If they are only to last 5 (?) years, I suppose retention toilets and electric doors would be asking too much. Yet those two changes are what are most needed.
Am I right that these are not yet fitted? Whenever I have been on an HST I have to go to the vestibule and close the windows left by people who last opened the doors, to stop the draughts. Over a year ago mind, so perhaps improved. I understood Chiltern had improved theirs.
Assuming the First Group order for the souped-up Class 800-type trains from Hitachi for the West Country is confirmed in June, all the HSTs will be gone from GW services by December 2018. Only if this order falls through and HSTs have to soldier on to Devon and Cornwall would there be any prospect of power doors and toilet retention tanks being fitted.
But in the case of the GW HSTs that are being taken over by Scotrail from 2017, they will be sent for a major overhaul, including the fitting of power doors and toilet tanks, before starting work north of the border.
