The issues you have with coach C are, the cubicles for the electrics which can’t be shifted, unless there’s going to be some radical strip out and rebuild of all the cupboards on the train. The TM cubbyhole which although now has less equipment, still has the emergency brake and the TMS for the reservations and such . CCTV and you will still have to include this somewhere on the train if you’re planning g on all getting the crayons out to redesign the train. The storage unit opposite the cubicles does also contain some electrical equipment too relating to the shop/coffee unit etc and also a water supply.
