Did you know that a class 165 visited Leeds once?
Would expect centre cars to be the same. Isn't the main difference that 166/168 are capable of 90mph but 165 only 75?
How inter-compatable are their systems? Could you put 165 centre carriages in a 166 without much work, and vice versa? Also I think I've read on this fourm before that they were built to allow convertion to EMU. Is this true and if so is it still possible, and how cheap/easy would it be?
165/166 combinations have been observed from time to time so it must be relatively straightforward to do. Over the years there have been examples of 166 centre cars inserted in 2-car 165s and driving car substitutions resulting in mixed 165/166 formations. They have generally been short lived.
I've tried all the usual places for information. I'm mainly after technical information. As I'm currently on a trainee drivers course
