Here's what I observed many times for speed control on passenger diesels in the 60's. Let's say the speed limit is 79. The engineer after starting would open...
Geoff, I suggest you download a demo (or purchase) one of the computer train simulators. Doing so will make it much easier for you to understand how a train...
