This should be pretty easy for someone but not me. I have my track wired and it works perfectly except one area. I have a branch line off of on of the large exterior loops in the interior of that line. This branch line works well and it terminates in a loop at the top of the hill (so the engine can dump slag). The area is pretty intense with switches going to a bunch sidings. To enter the terminal loop the left handed ross switch is set. Since there is only one switch the train needs to do one revolution of the loop go past the switch (which has now been thrown to the opposite direction to prevent derailment) and have the switch rethrown to the original position and then back down the hill. So the problem is this. The engine flies up the hill through all the siding switches goes through the last switch and now is in the loop and completes the loop. Half way through the loop the switch is thrown to prevent derailment when the loop is completed by the engine. Still no problems. It hits the ross switch a second time to complete the loop and the engine dies. IT DOES NOT derail. If I run it at non realistic speeds I can drive the engine through the switch onto the track which starts the loop (and worked fine when the engine entered it) and still the engine is dead, no power. My first thought is I switched the power and ground lines in the loop but no I haven't (which I sort of knew because the engine doesn't stop when entering the loop but only after completing the first lap). Thoughts?
