In terms of how much damage it does to a coupling, (talking modern DMUS an EMUS here) is it better for the first set to power up first are the second set?
So is more damage done in compression or tension? I wondered if there was a way round which was better and that when units are joined this is automatically what happens?
Now im sure its better they power up together, but i have noticed recently it seems like the seperate units power up at different times.
Not only that is a 158 and 150 are connected they will have different accelerations surely?
