Thanks all- the original transformer is from a DC powered set (pic attached). This one stopped working one day after setting it up after being packed away for at least 30 years. By 'stopped working' I mean that there was no action occurring at the track to either the locomotive or to a crossing gate. Thinking the issue was at the transformer level, I bought a new one (the CW-80). This one, as described above, definitely supplies power to the track, but the only way to get the locomotive to move is to use the 'whistle' button, and even then it barely moves. And when it does, there are a lot of sparks between the locomotive wheels and the track.

Thanks,
Mark
