Thomas the Train Ride on Train only goes backwards

The only thing left is the motor or the controller. So you isolate the motor and connect it to power. If it turns are full speed, you know it is the controller, if nothing happens it is the controller.

It's possible the contacts on the battery are bent, so when the trains moves the contacts lose connection with the battery.
remove the battery, paying attention to whether or not the contacts are tight on the battery. Use a small screwdriver to bend the contact out, so it pushes on the battery with more force.You may need to fold up a small piece of foil and put it behind the tag to keep contact with the battery.Typically there is a spring on one side of the contact and a small copper tag on the other. if the tag cannot be bent outward, you may need to use a pair of needlenose pliers to stretch the spring out -be careful though, you could break the plastic mount for the spring which would ruin the train and give you one unhappy conductor!
Hope this helps and thanks for using Fixya!!

First, check to make certain that the batteries in the remote are good.
Second, if the train has been running and the problem is new, clean your wheels and pick up roller on the locomotive, then clean the track.
Make certain that when you use the remote, you orient the antenna in an upright position and are within 6 to 8 feet of the locomotive.
If none of the above helps, contact the Lionel Service Department.

funny, you can fix this real easily, you just need to flip flop the cables on the motor, currently the polarity is reversed, theres only two wires connected to the motor just switch them around

A few things can cause this: The battery is weak/bad. The connector at the battery might be worn out and have intermittent contact. Those are fairly easy things to check. Next, the GO button might be worn out internally (high resistance contacts)-believe it or not, the whole motor current goes through that switch. You would need to remove top of the roof to access the button. Or, open the speaker cover, pull out the control board and bypass Go switch wires to check for train proper operation. As you are already there, inspect the control/sound board. The last thing that comes to my mind is the motor itself, it is under the seat. Check contacts to motor, plus you can spray contact cleaner or, if you don't have anything else, alcohol. Avoid using WD40 - it does the job, but collects new dirt very very fast). There is always a chance of pinched/loose wire, or mechanical problem with gear assembly/jamming or so.

have to hold on the button that has arrow untill it moves

It might need a new wire connection to the motor.

Hi

Have you tried keep pressing the right hand button down. When you press the button down and hold the press, then the sounds are finished, the trains starts driving. When you release the button the train stops at once.

I cannot promise that this is the problem, but this is where mine was broken, and you may be able to fix yours this way.

I was able to remove the plastic around the tender and access the motor. Using alligator clips, I was able to connect the battery directly to the motor, bypassing the circuit board. The motor functioned, therefore the only component that seemed to be defective was the circuit board, located behind the speaker in the engine unit.

As far as I know, the only place to buy a replacement circuit board is from www.tigerimports.com. Search for part number MEVA0024. Cost is around $15 + shipping (around $6 or so).

I should be receiving this part by the end of the week and will report if it fixed the problem.

Thanks for using Fixya. If I didn't help your situation, please DO NOT label this advise as "inappropriate".

The red button on the right must be held down for anything to move. It turns the lights on, makes some train noises, then moves forward. If you don't hold the button down, nothing will happen. Note that when the train is underway, the left red button becomes a train whistle. Otherwise, when the train is not running, that left button produces music. Hope this helps.
