One type of battery train set that I felt deserved its own page is what I call the "Small Scale" set. I'm categorizing these sets on their own as they have been produced by numerous manufacturers over the years. These trains use a single 'AA' battery and are driven by a vertically mounted motor on the rear axle. There are 4 classic designs for these trains, and there are a couple more currently being produced in China.
There are two main types of track seen with these sets as well. Some sets come with a roadbed style track and others are a more fragile track. The roadbed style track has offset connectors to allow a wide range of track designs. Curves and turnouts are 90 degree corners. Some sets using roadbed track also have 90 degree crossings. The other style of track is much more restrictive, only offering a 180 degree curve, a dual switch piece, also 180 degrees, and straight track. This style of track has wide spade connectors and can only be connected one way.
Versions of these sets were imported by Durham, Echo, and others.
