Track problems -- short circuit?

[GreenDiesel]

Thanks for your feedback above! But I just found out what my problem is. It was the Atlas #205 switch. The 'port' on the far left where the wires join in bad. Once I disconnected the wires from that port and used the middle one, everything worked fine.

Only problem is that the middle one was used to give power down a siding. Will have to get a new #205 this week.

Thanks again.
