The BBT Drive is designed to improve the Bachmann Big Hauler and it's abilities to pull a large number of cars, easily, realistically, and trouble-free.

The highest quality materials have gone into the production of the drive unit. The design has been developed to make the installation as simple as possible. There are areas which will require your diligence and patience, so take your time.  If you run into trouble, please call us. It will be helpful to you to read all of these instructions before beginning the modifications to your Big Hauler.

This instruction set is made up of several sections which will guide you in the sequence of the conversion. As previously mentioned on the order form, once you begin there is no going back.
