Maxitrak Simplicity II battery locomotive - one of the classic Maxitrak designs which they produced until around 20 years ago. This is one of a pair that have arrived with us recently.
Steel chassis with fibreglass body.
12v motor with chain drive to axles.
4QD DNO-10 controller with handset.
Loco appears to have been stored for a while so will require a tidy up and recommissioning.
