This teardown is not a repair guide. To repair your Thomas Ride On Train, use our service manual.

  1. System Components
    • System Components

    • When power is applied to the charging connector it activates a relay which disconnects the power to the main circuits.

    • The main powerswitch is under the large yellow lever and simply applies power from the battery to the control board in the console.

    • A multipole switch is used to reverse the direction of the motor

    • An LED in the console flashes with the sound

    • The sound is provided by a loudspeaker in the base

  2. Charging Connector
    • Charging Connector

    • The charging connector is on the rear of the train between the buffers

    • My connector is a "old style" connector which is effectively a phono, the new style is a more conventional power connector

    • Power Switch and Charging Relay Board

    • This battery has been replaced, the originals attach via a clip

    • Note the fuse on the positive connector

    • This switch is controlled by the level on the console and switches the polarity of the motor connectors.

    • Middle position is off, the other two positions are forward and backwards

    • If you are replacing the LED don't forget that the polarity of the wires is important

    • Has three switches to activate the music and connectors leading off to the motor, speaker, LED and battery

    • This is a 16ohm speaker

    • 6v electric motor with capacitor for noise and spark suppressor wired across the terminals

sound their but it's stoped moving

If you've got sound but no movement then the most likely cause is the battery is discharged or defective. If you have a multimeter you could check the voltage on the battery.

If may also be a motor / mechanical issue. With the power disconnected you should be able to rotate the wheels but it won't spin freely as there is a gearbox.

Movement but no sound? Been charged

That could be a problem with the sound board which lives inside the steering wheel. It's quite a challenge to get to that which is what caused me to write the guide in the first place. I had to clean the switches on that board to get mine to work.

Alternatively could be a loose or broken wire on the speaker which is down in the base, one of the first things you get too when stripping it down.

What do I clean it with? Just polish? Had a look. Wires look fine so im confused lol
