Some coal transport trains in West Aus run with >100 coal trucks, and have loco
groups at multiple spots along the train in addition to the front. They also
have problems on hill-crests, where the lead locos must reduce power going down
the far side, while other locos still climbing must still be powered, to avoid
breaking couplings. And the opposite in valleys. Luckily the landscape in the
areea is such that there are minimal crests & valleys 8?)
