With regard to disability access. Having been offduty and having seen my contact working one have to deal with this - it is extremely badly designed. The floor heights are much higher than any other WMR unit sofar and on curved platforms such as at New St and Telford, the gap is insane and has to be seen to be believed. The 196s have to have their own special ramps, so station ramps suitable for 170s, 172s, 350s etc are out of the question.
Worse still, amidst the piss poor implentation of the 196s onto the Shrewsbury and Hereford lines, station staff at Wolverhampton and Birmingham have not been / refuse to be trained on them meaning the conductor onboard has to do the ramps. Grab a coffee, it gets even worse.
The ramps will only work in one pair of doors each side of the train. So on a four car set with 2 doors each side, of the eight doors, only one door can have the disabled ramp fitted properly. They're usually at the end of the train. Which, on the longer-carriages-than-previous units, coupled up to the fact guards can only control the doors from the rear cab [no saloon panels!] means if the disabled carriage is at the driver's end, the guard has to walk all the way forward to nearly the driver's cab, get out the ramp from a tiny access cupboard situated right where the access toilet control buttons are, and then unload the ramp. Oh, and the "bridging plate" is in a separate cupboard, held in place by a very awkward ratchet strapping.
The time lost by having to do what should be a simple, but absolutely vital duty twice [on, then off] is mind numbing. It is as if WMR doesn't want disabled passengers travelling on its shiny new units.
