Except for a brief moment as the train crosses the gap. If the power
packs are set to close to the same level, there really shouldn't be any
problem with having them electrically connected. They'll just equalize
out the voltage, in part by dropping the difference across the internal
resistance (and the intervening track resistance). Sometimes the fact
that we don't have ideal power sources is a benefit.
