Hello,

I'm new to these forums and must confess to knowing very little about trains in general despite holding a strong interest in them, however I do have one question that i'm sure can be easily answered.

Last night whilst waiting for my train to pull out, we were sitting next to a set of carriages with a diesel locomotive at each end. I've often wondered, how are the two diesels connected so as the control inputs from the front loco is repeated in the second?
