Sorry, I didn't know the terminology, I just meant that I only tested with the section of the track that you plug the power supply into (terminal track, I'm guessing?) to rule out any issues with the rest of the track. And yes, that is the light that flashes when I place the locomotive on it, all other cars work fine, the light stays solid. I was afraid there was probably an issue with the locomotive, I'll call them in the morning. Thanks for your help.
