Start-up
Solution
When I apply power to the
track my engine doesn’t do
anything. No lights, no
movement, no nothing.
Check to see if that section of track has
power. Use a voltmeter or a lit passenger
car.
Slide the engine a couple of feet in either
direction, you may have a bad track section
Have you got that section electrically
isolated with a toggle switch or other
device?
