Things You'll Need
Instructions
Examine and clean all electrical contacts. Focus on the locomotive's wheels, contact rollers and sliders. Dirt and grease in these sections act as insulators and slow the train.
Dampen a cloth with train cleaner. Extensive use of the smoke stack can leave a white reside on the locomotive's body. Gently clean the body.
Remove the locomotive's top with a screwdriver. Examine the motor. If it is dirty, the locomotive can run unevenly and sluggish. Find the commutator -- the carbon brushes make contact on this segmented copper surface.
Place the locomotive on its side. Connect one transformer wire to the locomotive's contact roller. Touch the other transformer wire to a metal section of the locomotive body. The commutator begins spinning. Press against it with a small piece of fine sandpaper.
Clean the commutator slots with a toothpick. Clean and lubricate the entire motor and assemble the locomotive.
Return the train to the tracks and test again. Start on the tracks closest to the transformer and run the train slowly around once. If the train stalls examine the track checking the connections.
