I bought a Tyco 630 Delaware & Hudson at least 10 years ago. It was in it original box with the handrails pack.
Tonight I wanted to change the traction tires. I noticed that the old traction rings were perfectly clean, but hard. I placed a tiny bit of oil on the motor shaft but when I put the pieces back together, it would only light but not run. It makes no sound from the motor, no buzz, no squeak & move.. nothing.
I had placed it on the track a couple of weeks ago and it only lit up. It was definitely NOS and never used. So what needs done here?
Also tonight, I oiled and placed new Traction tires on my Illinois Central 630 and it runs and pulls like a champ. However, it did run slowly from the start when I got it out of storage.

| Have you tried applying power directly to the motor brushes? If the motor runs this way you know you have some sort of interruption from the wheel pick ups to the motor and have a place to start checking things out.

First thing you should do is take the shell off, and see if the motor will turn over by hand. It could be stiff from lack of use all these years. If it does turn over, then apply power directly to the brush holders, and see if the motor powers up. If not, then it must be the brush/armature connection. Grease in the axle area can harden up and stop the wheels from moving, but if you hear no sound, I'd open it up and check the motor directly first.

I took the 630 apart today. I took the power torque motor apart. I noticed before taking apart, the armature was tight and would turn, but not freely. Apart I wiped the pieces off, they weren't dirty but did it anyway. Reassembled the unit with all cleaned and lubed axles . Everything worked as it should. Touched wires right to the brush holders and still not a grunt. Light still works well!

did you try running it with the gears removed just running the armature with no loading.
check for hair clogging up the behind the pinion gear.
did you pull the brushes and spring out, and give them a cleaning.
brushes can get contaminated just like the armature. the Slot car method of cleaning is rub the face of the brush on white paper to polish them.
did you take the back plate off the motor and give it a spin to see if it ran free then.
last, you can take an ohm meter or a continuity tester and test the motor coils/windings touch the commutator poles 2 next to each other and run the test 3 times if any of the coils are broken then the motor will either not run or run poorly, it is possible to repair them before attempting to rewind them. but first make sure all 3 coils are good on the armature.
you will want to also make sure the brushes are not getting hung up in the cup holders.
you can also try holding power to the motor and spin it by hand and see if it kick starts.
test with a 9 volt battery touched to the brushes and see what happens.

No OHM meter, but tried all the other ... Just puzzled that this thing shows no signs of life. It's an NOS never run piece...

Could be a dead motor/armature. I'd unload the motor, take the pinion gear off, and see if it'll try to turn with direct power. If not, could be a bad armature from the factory, check the solder connections at each arm, see if they're corroded, green, etc. There's not much to go wrong, so it's either binding, or there's an open somewhere, if you're not even getting a hum from it. The other thing , although unlikely, is that the magnets are dead. Dead magnets, no electrical charge. See if a screwdriver will stick to them.

I took the 630 apart again this evening , checked the magnets and they seemed fairly strong. Carefully reassembled and still had no power. I had damaged my Santa Fe 630 as it's box feel out of our trailblazer when I opened that hatch sometime ago. I tested that motor and then transplanted it into the D&H. My only complaint is the connector broke off when it fell, so I have no front connector on it.
I will buy another Santa Fe sometime in the future...
