Why would a TOC spend a considerable amount of money on PRM works for coaches that would see only a few months service then handed back to probably be scrapped?
They've had them for quite some time - the works required are minimal given the spare coaches were readily available. In any case, it would not have cost a 'considerable amount of money' to do the bare minimum.
Look at the Mk2 and DBSOs being used on the Cumbrian Coast, the adaptations there are minor. Sure, it's hardly a brilliantly accessible service, but, it's better than nothing. Again, no one was ever going to expect PRM-TSI compliance (or even RVAR), whether this service had rolled out a year ago or today it was never going to be compliant, nor did it need to be.
As for taxis, are rail replacement different from regular taxis? If not then yes I have used taxis, in fact I used one yesterday, I've used them to come home from Manchester Airport and so on. But if taxis are not a credible solution, then what happens if there are busitutions in future? Do TOCs cancel these because they may not be PRM compliant and some people don't like taxis.
Buses can be accessible, if the TOC books the right vehicles (they often don't). Taxis are fine for most, but, the availability is a problem - the TOC contracts through Cabfind (Cabsi) and others often do not use local firms meaning a taxi is coming a considerable distance and is often late, or, the driver has absolutely no knowledge of the area they are taking the job for.
In my own experience, on a recent Glasgow > Carlisle taxi the driver couldn't find the station because he had no knowledge of the area - similar on the return, except for the fact that the taxi was extremely late owing to an argument between TPE & VTWC over who was to pay for it - I kid you not. Or, to look at another forum member's experience - over 40 minutes at Windemere yesterday, despite having
pre-booked assistance with the TOC because the taxi simply didn't turn up (and, the TOC's buses were inaccessible).
But don't just discuss this here, please feel free to find one of the many services rammed full and explain to people stuffed into a corner of a vestibule that this is a much more preferable solution than a few passengers being forced into cars. Like I said, I'm sure they will fully understand.
Again, I sympathise - but, this isn't the fault of the disabled people, it's the fault of an incompetent operator agreeing to do something that was never going to be wise. Had it already been in service and running for some time then the scenario would be "when is this going to improve?" (look at ScotRail's Fife Circle LHCS services for example - inaccessible, have been in operation for donkeys, will be going circa next year). but, to willingly roll out a service which is actively blocking certain groups from using it is unacceptable, and, could have been so easily done differently.
If frustrated folks want someone to complain at, the MD of TPE would no doubt be delighted to hear from them. Or, equally, Messrs Grayling and Johnson at the DfT, whose inept department are the source of many of the (historic) issues with TPE.
As an addendum, it might be helpful to consider that PRM doesn't just mean a person in a wheelchair. The
definition is a bit more complex - '‘Person with disabilities and person with reduced mobility’ means any person who has a permanent or temporary physical, mental, intellectual or sensory impairment which, in interaction with various barriers, may hinder their full and effective use of transport on an equal basis with other passengers or whose mobility when using transport is reduced due to age.'. From a technical standpoint you could also consider folks travelling with buggies in a similar respect - it may not be easy or practical for them to store the buggy as luggage - they currently have a space on the 185, but, wouldn't on a Mk3 without occupying a vestibule and causing inconvenience.
