Whether you’re converting an OO gauge RTR model to P4/ EM, or are looking for much-improved performance and prototypically correct detail, these kits provide the components you need to build a completely new chassis for your 4mm scale steam locomotives.

High Level PowerPacks are custom-designed to fit specific proprietary models and include sideframes of prototypical outline, with optional cut-outs for our own High Level Hornblocks. They include OO/EM/P4 chassis spacers, full spring and brake gear detail, coupling rods and dummy inside motion, as well as cosmetic detailing parts.

Each kit comes complete with its own bespoke High Level ‘Precision’ gearbox which is completely concealed within the structure of the locomotive. The mechanisms feature double-reduction gearing to give you enhanced controllability with superb smooth low-speed running.

We also stock a range of motors to complement our traction packs
