Hartland Locomotive Works - 45mm Gauge Mack/Isolated Motor Blocks

These self-contained power trucks are used by Hartland under their Mack and Sparky models. Suitable for up to 18 volts, they are simple, robust and ideal for scratchbuilding. Wheelbase is 3 inches (76.2mm), with 1.5 inch (38.1mm) wheels - see the datasheet(s) for details.

The units pick up on all wheels and drive on both axles. As used in HLW products the blocks have internal hardwiring between pickups and motor - easy to use, but unsuitable for DCC etc. Our 161-H2xx series conform to this wiring standard.

Alternatively we also offer the 161-H3xx range, which has the motor isolated and all the connections brought outside to a flying lead plug/socket. This allows the user full flexibility in wiring for DCC, battery, running motors in parallel/series, etc.

Please note that the axle ends are NOT suitable for use as journals, and the unit should be supported using the the centre pivot or mounting tabs provided.
