AHR Aerotrain manufactured in August 2002
Engine with one self-contained DC power unit
One of two cars or coaches - look like a bus? That's what they were based on.
Tail fins anyone?

Extra weights more than doubled the original weight
Weights added rail contact, but loosened half-axles in drive gears
Partially disassembled power unit
Power unit without can motor and contacts
Tip of half-axle "knurled" for better bite into plastic drive gear
Nylon set screws could not be removed
Added weights removed. Runs well without them.
Engine dated and initialled
Underside of a coach
Simple but effective design
The real Aerotrain...
...with two cars
