What it really needs is a holdover button like we had on 175s. Why we aren't trusted to be in control of the brake is anyone's guess. I'm not sure if there's any practical remedy that can be made - maybe lower the threshold at which the brakes will release? Most of the time, the train will move at the lowest power setting - but if it's heavily laden it requires more power, and there's noway of knowing if you've given it enough until the train starts moving.As a passenger it is noticeable that a lot of power is applied just to move off, despite slippery conditions leading to inevitable slippage. Your explanation explains why that is. Surely a design flaw that needs remedying?
To be fair, the Cheltenham services can be very busy, and as has already been pointed out, a 4 car 231 doesn't give that much capacity."Smaller lines" apparently including the Shrewsbury-Holyhead leg of the Birmingham services. Whereas the Cheltenham services will be formed of a four car 231 even if they're carrying one man and his dog.
I'm still not entirely convinced the 2 hourly 2 car Birmingham - Holyhead service is in the long term plans anyway.
I'm surprised by this, given those are the routes they're actually designed for! It might explain the rumour (since debunked) that they were looking at fitting pantographs and sending them to Manchester. We can but dream.....Not sure why the obsession with 231's though. Their fuel range is terrible and they won't even be able to do a full days work on Ebbw Vale and Maesteg services without dropping in for fuel, never mind long distance services away from their home Depot - They are Stadler, not CAF units.
And of course, whilst there are plenty of routes that next extra capacity right now, there are also plenty where a single 197 will provide more than enough capacity for years to come.But there will be fewer options for service recovery. A large fleet of DMU's will provide more spare cover. A smaller fleet of 5 car trains means fewer spares, reducing your options when things go wrong. They will also be fewer options across the country to recover the service when things go wrong. Under the current setup there are 197's all over which can step in and cover.
