Created an activity where a long/heavy player driven consist is to stop just forward of a siding where two helper locomotives are waiting to couple to the rear of the player driven consist. Once the two locomotives are coupled to the player driven consist, then the new consist configuration proceeds up a hill.
What I'm wanting to do is to switch to the lead locomotive of the two locomotive helper set to drive the helper set and couple to the rear of the original player driven consist.
But there doesn't seem to be any (key) combination that allows switching between different locomotives OUTSIDE/APART from the original player driven consist!? The key combination Ctrl and E only enables switching between locomotives within the player driven consist.
Is it possible to switch to other (driveable) locomotives that are separate from the player driven consist? If so, how?
Thanks.
