Power to track Problem

[selector]

I think the above suggestions are bang on. If had been been careful to not mix up the leads, I would cast a jaundiced eye at my power pack. Unless, something on your loco is hanging down across both tracks. Did you test with a tester or with a loco?

uptowntrain, Sounds as if something is shorting out somewhere. Recheck all your connections as you may have accidentally switched polarity with one of them. Disconect the wires one pair at a time and see if the train runs. If it runs then you had the wires hooked up wrong. Do you have a reversing loop in the system? Sounds like you don't, just athought. Good luck!

is the power on?....that's usually the problem....are the wires connected to the DC side of the power pack? ....turn the pack on and take a multimeter on the 50v DC setting and touch them to the terminals on the pack, the wires from the pack to the track and then to both sides of the track until you find the rail joint (or any other component) that's not allowing the juice to flow ...it could be a faulty power pack, a wire not making continuity, a loose rail joiner, really dirty track, wires not connected to the same side of the track or a defective locomotive motor ...Chuck

I'm building a small N scale layout in a coffee table under glass with a tunnel of course, because of this I want power to three points on the track (there are no switches or crossings) I assume the way to wire this back to the power supply is all outside tracks to one power supply terminal and all inside connections to the other terminal? I tested the connection using only one of the powered joints back to the power supply, it worked fine (it was soldered). When I joined up all the track connections, outside rails together and to one transformer terminal and inside rails together and to the other transformer terminal I got nothing. Is this telling me I need to solder the other two connections.
Thanks
