Had the opportunity to ride on the four car
HST▸ set between Plymouth and St Austell last Friday.
The set is currently topped and tailed by two of the green power cars. 43187 (still branded Y Cymro/The Welshman) and 43016
The most obvious difference from the outside is clearly the automatic doors
The doors, which open smoothly and without delay when the button is pressed, slide into an internal space rather than "popping out" like the 158s or sliding externally as with the 153s.
Internally the coaches look very similar to the full size HST set launched in 2016.
The coach I was in only appeared to have two sets of four seats around a table. Powerpoints and wifi are provided throughout.
The toilets now have retention tanks (I don't do photos of
WCs▸ !) This first set is lacking a disabled toilet or a wheelchair accessible space.
The automatic doors certainly help with dwell time and we waited for time at a couple of stations. Partly I suspect due to the shorter station stops but also the better acceleration.
One thing which caught my eye was the requirement to only fill the tanks on Coach A with drinking water - the other three have no such requirement.
Is it because the coach has been converted from a former catering vehicle, or is it required for the train manager's office?
