Please help! My husband received a Lionel train set. We are thinking it is a 72 model. There are no numbers on the train other than the 8042 which is clearly the train number. We found it boxed and stored. We want to get it ready for Christmas for our grandchildren to enjoy. It runs in reverse motion. When we move the switch one way or the other it doesn't matter. It will go forward a couple of inches and then change to reverse again. What can we do to fix it.

easiest thing to do is keep trying. It may start working.

Christmas is a few days away and a repair shop (if you can find one near you) may be able to repair it before then.

There are several 8042 locomotives on sale on ebay, but delivery may also be too late for christmas.

Is the track clean and tightly connected?

When the train runs in forward, stop it. Then switch the reversing switch. It will stay in forward.

One way that may fix the E-unit (reversing unit) is spraying it with CRC contact cleaner (HD electrical section). Then switch the power on and offer several times to cycle the E-unit. Repeat as necessary.

Note: the E-unit will only cycle with the loco upright.

Given it's used and already has a problem, I would use the CRC to clean the entire Loco's drive train (motor, axles and bushings, rollers and brushes). Liberally spray the entire drive train (over newspaper) and run the engine. Repeat as necessary as old grease hardens and needs to be flushed out. Then lube with a lightweight oil (3-in-1, sewing machine oil, etc). In a pinch some auto motor oil will do. And you can use Vaseline for greasing the gears.

If it still has issues (sluggish), you'll need to clean the motor's commutator and brush assembly. Not as hard as it sounds but that requires removing the motor from the shell.

I do believe that you might as well tell her in Greek. :p

I think that she won't have any clue as to what you are talking about. Maybe the first sentence but not the rest.

Welcome to the forum!

Your 8042 locomotive has a 2 position reverse unit.

With the train running forward, push the lever on top of the locomotive to the opposite direction. That should lock the locomotive in forward. If it does not, the reverse unit may need servicing or replacement.
