The 5" gauge Jasper is a robust powerful battery electric locomotive which is equally at home on garden and club railways. The freelance style was designed to fit one standard car battery under the bonnet.
12 Volt Version

Designed for one 063 type car battery. Top speed of 6mph. Ideal as a beginners engine or for younger children. The 2 motors give enough power to comfortably pull 3- 4 adults but for some the top speed and reduced power may not be to their liking. The 4QD VTX 75 amp motor controller is an over specification ensuring that board is not put under strain.

24 Volt Version

Designed for two 063 type car battery. Top speed of 10-11mph. Don't be fooled by the small size. The 24v version is a wolf in sheeps clothing. Due to the physical size of the Jasper there simply isn't room for horns and accessories. We can fit just one single note motor bike horn as an optional extra.
Motor controller is the iDrive with all its features and rated at 120 amps for continous use you never need to worry about motor control issues.


 With the batteries and body removed the chassis weighs just 23kg which means it can be easily transported in nearly any car.

Q. Is it OK to use car batteries? - A. Yes. Today's batteries are far more robust than that of 10 years ago. In heavy use you can expect to get over three years use, possibly longer. While traction batteries are designed for traction purposes, they rarely out last car batteries. Costing over twice the price the often prove to be false economy.

Q. Why don't you powder coat the bodies? - Powder coating can be a more durable finish but it does have disadvantages. If damaged it cannot be repaired. Acrylic car paints offer the advantage of being able to be repaired or overpainted. It also means that the average person can repaint a body to give it a total new lease of life.
