but the contact pads are worn completely out.
there is no on/off switch on the train. power goes from wall plug to transformer, then from transformer to track clip, which must be attached to the track. a control line goes from the track clip to the controller. mine has a green light just above the red on/off button that will come on even if the engine and tender are not on the track. the tender does all the work, and must be connected to the engine and on the track. there are four sliding contacts between the tender wheels that provide contact with the track.
we have no parts for sale here
