    It should be 160A not P. The 141Ps and 241Ps were new designs. Chapelon rescued the 241P after requests from Creusot but the frames had already been cut and were too thin which lead to hot axle boxes throughout the life of the locos.

    Not really, it is a matter for the infrastructure manager of the railway in question. The NYMR is independent of Network Rail. It is up to them to have their own risk based decision, based on whatever mitigations they have in place. I can't...
