I have a new bright animated holiday train from a garage sale and I think I am missing a power cord

You should have a 3 pieces to provide power....

1. A track connector box. Looks like a "T". It slips under the track to make the track power connection. The transformer plugs into it (2 pin Molex type connector) and the command console (has an RJ11 telephone jack type connector on it)

2. A large square transformer. One end plugs into the wall and the other into the track connetor box.

3. The Command Console. Has the on/off button, forward, reverse, mute, sounds and speed contol on it .. has a connector that looks like a telephone plug.

Unfortunately... DO NOT look to New Bright for missing or non working parts. New Bright does not offer repair or replacement parts for thier products. :-( ....
