TP09 has now been accepted by TPE and the diagrams are the start of driver assessor training. The CAF Bletchley runs should start again Wednesday with TP04.
I have been told by well placed sources that set 09 was accepted to enable staff training to commence, but that it will not enter passenger service in its current condition as there are still some issues to address with the set. Hopefully other sets accepted are fully ready for passenger service.
