Hi
We're about to add a second 9V train to the family and that raises the question of power. I know you can run them both on the same track at the same time if you're ahppy with them going together. We're thinking of having two separate tracks with a connecting siding between them in which we'll cut an isolating break. But the question is, if we make a mistake and hook things up so that both power supplies get connected to the same piece of track, what damage protection is there in the power supply or motor to prevent anything nasty happening?
