    Default Model Power 4-4-0 No Traction

    Hi all! Got a brand new MRC Model Power DCC 4-4-0 steam loco and Atlas starter track kit till I figure out what kind of layout I want. Loco in spots just spins, put a couple of cars on it and forget it, won't move just spins. I watched youtubes and read reviews and never saw that this was a problem. Am I doing something wrong or did I get a lemon?
    Thanks

    The DCC version should have traction tires on it which makes these quite reasonable pullers for their size. Keep in mind this loco never pulled a long train, even in real life. It was meant for local passenger service with maybe 4-5 cars at most.

    Do you have any grades? is the track level at the joints? Vertical curves/kinks in the track are worse than radial kinks. If the track dips and dives too much, it will lift weight off of the drivers and cause traction and derailment issues.

    Track is on a flat board. I tried 1 boxcar and 1 caboose. No derailments, just no movement. Only the front to drive wheels have the traction bands on them. I will check where the rails join, but it looks level.

    This is going to sound stupid but is their packing foam under the pilot truck lifting the front of the loco up. I've seen it before. Could be too much spring pressure on the pilot truck. Could also be the tender pulling the back down. All the weight of the loco needs to be on that front driver.

    Turn it over and check that the wheels on the pilot truck are free spinning and those on the tender too. I belive that it has sprung wipers on the tender axels. Check that these are not too tight or bent. Also, check that cars you are pulling are free wheeling.

    Let us know how you get on ?
    Thanks, Tom

    Expect nothing except the opposite of what you expect, and then expect it to be something other than that ! Then that's about what it will be

    The most recent production run does not use axle wipers on the tender. And if it has traction tires on the forward drivers, it is from the most recent production run.

    A common fault is the drawbar between the loco and tender. In your case I would look to see if the drawbar is bent up at the front.......that would tend to lift the rear of the loco and you end up with the loco resting on the front truck and the tender wheels. My MP 4-4-0 runs well and pulls 6 or 7 passenger cars on level track.

    Not stupid and very very close! It was a small piece of black foam wedged between the cab and the tender. I obviously need more light in that room!!! Thank you for making me take a harder look and thanks to everyone else who offered help.

    The foam peanut was used to prevent damage to the drawbar when removing or replacing the loco in it's case. Keeps the loco to tender connection straight. And yeah they run better without it, had that issue with my 1st 4-6-2.
