  • The thing is that the short only occurs when a loco is over the frog; if there was a problem with a closed gap or errant solder, it would short as soon as the track power came on, right?Nevertheless, I performed a visual inspection this morning and found that one of the power leads I soldered to the underside of a rail might have been too close to a copper plated tie and created a circuit.
