i hve to be honest the NVR isnt the best preserved railway.
its ok if you dont mind traveling in forign caraiges with the floor falling out of many of them.
but the benefit is that thay have an operational 56...
and come the diesel gala... 2x class 56's which make it worth traveling for..
plus normally GBRf contribute a 66 or as last year a pair of 73's
