My TYCO 2-8-0 doesn't run after I made the misake of taking it apart. The motor runs and headlight lights if I hold one lead from the power pack to the tender pickup wheels (which pick up on one side only) and the other lead to the motor. Apparently, I have continuity from the tender wheels to the motor and the headlight. I suspect that the brush or pickup which picks up power from the locomotive drivers is missing. Does anyone know where I can get these and how to install them?

Before you go to all that trouble I have a question or 2 or 3.
What happens when you put the loco on the track? Does it short out the transformer? Does the light light?
Did you remove the wheels from their housing when you cleaned it?
My son was a great one for not putting the wheels back properly, no matter how many times I told him to watch how he takes the out and put them back the same way. It does matter which side is the insulated side and has to go back the same way.
Just a thought before you go to all the trouble of looking to buy parts.

It may be that the tender chassis is backwards and the pickups on the tender and the loco are picking up from the same rail.
Also check the wire to the frame of the loco.

Don't think "Mistake"...think "Expanded Horizon", "Marketable Job Skill" Those folks are leading you in the right direction. I just had it happen to mine, turned out to be a missed brush spring...I could hear Ray chuckling through my modem as I wandered though carpet purgatory to find it, too.

When I put the engine on the track I get no response. The light does not light. I did take off the bottom plate that holds the wheels in, but the wheels were never disconnected from the driving rods so they have to be back in the same position and orientation. I will check to make sure I don't have the tender chassis in backwards. I will also check the wire to the frame. Finally, what is this brush spring? Are they available anywhere?
Thanks,
Landon

I have checked and the tender chassis is in correctly. I have also checked the wires to the locomotive frame. The disconnect appears to be between the frame and the drivers. Shaygetz mentioned the brush springs may be missing, but I don't have them. Does anyone where I can find some and how to install them?
Thanks,
Landon

I once belonged to a club down south...
I was told: "If you don't know why it doesn't work, drop it to the floor. Then all answers will be found as to why it doesn't work."
I didn't follow such advice.
I don't have a one track mind. It depends on the turn-out.
"I love your catenary!"
Is that a power-trip or just another pick-up line?

| I believe Athearn brush springs would work, one cut in half should do it for both. The brushes hide behind those little "paddles" on one side of the motor. Be patient or you'll send them off to carpet purgatory.

| It sounds like you are speaking of the brushes on the motor. However, the disconnect appears to be between the drivers and the frame. How does the power get from the drivers to the frame?

| On the tender, those silver/brass wheels should be on the opposite side of the frame from the geared wheels. This is how it picks up power in the tender. On the engine there is a pickup off of both side of the drivers.

After some more investigation, I have discovered that If I push the engine (not the tender) slightly to the right, so that the right hand drivers are pressed against the rail, the engine will run until I remove my hand. I know the tender wheels are picking up power, because if iI hold leads from the power pack to the tender wheels and the locomotive chassis, the motor runs. The tender pickup wheels are on the right hand side, so the engine should still run if the right hand drivers don't pick up power. I know this is counterintuitive, but somehow pressing the right hand drivers against the rail allows power to get from the left hand drivers to the frame. Any Ideas? Thanks,
Landon

I you haven't already done it I would remove the bottom cover of the locomotive and check for corrosion or carpet fuzz on the axles and journals.
There are also brass jumpers from the rims to the axle that may loose contact.

Many thanks to all who offered suggestions. Special thanks to Ray Marinaccio for his suggestion to clean the axles and journals. I didn't have anything small enough to reach into the journal, but I cleaned the axles with my Bright Boy and THE ENGINE RUNS!
Many Thanks,
Landon

Glad to help.
Sometimes tracking down electrical problems can be frustrating.
