When we have to deal with something at the rear of the train, especially SPG setting up or detaching the helpers... 1. Please stop it with the pop up message every few seconds asking if we want to relinquish control. No, we don't! We are performing part of the scenario walking to the back of the train - give us a key command to call up the prompt if we do indeed want to relinquish, or an option to not be pestered for xx minutes. Or... 2. A fast travel to/from front to rear of train so we don't have to spend 5 or 6 minutes sprinting along the ballast. Ctrl = or - doesn't take you to the rear loco set and even if it did, can't use it to get back once the helpers are off. I can see this potentially being an annoyance on Clinchfield, too.
Strange as it seems to pop up every couple of minutes on SPG, though I have noticed on other routes where you *want* to abandon the train, it doesn't. So as I said something that should be under user control.
