The vast majority of stuff on the railway is done using the humble T-Key. However I've noticed as a conductor that on newer stock the variety of keys needed increases.
Simple example, almost everything on a 156 needs a T-Key, nothing else but then on the more modern 170 I need a T-Key, CDL key and Southco key. But the drivers key always remains as a constant regardless of what I have to use.
Is the drivers key universal to all stock in the UK? The 170s are the newest things I work on professionally but what about things like 70s, 380s, 390s and 395s? Is it still retained on yet to be delivered stuff like IEP, 68s etc?
