I think you are mistaken about what the derogation process is ... and what is allowed for. It allows for thing like button being a few centimetres outside the requirements. Derogation certainly doesn't apply for wholesale changes that were not made due to completly shambolic planning.I wonder if derogation will be granted for Pacers/150/158s. TFW only started PRM Mods about 6 months ago and have 60 units (24 x 168s and 36 x 150s) to be completed. At the moment there are only about 6 of that that have been done. The clock is ticking. They will still have to go to Works whether the 769s ever come or not
If TfW operate trains that are non-compliant after deadline, they risk being taken to court, prosecuted and fined ... and can see at least one disabled body undertaking this course of action if these events arise.
You would hope KeolisAmy recognised this risk, and factored it in finacially to their bid, or there was an undertaking for any fines to be based on to the Welsh Assembly.
