USA Trains 45mm Gauge Motor Blocks

These self-contained power trucks are used by USA trains under their range of American outline diesels, and make ideal and economical running gear for either modern diesel and electric outline locomotives, or older units fitted with tramway skirts.

The units pick up on all wheels, as well as the slider shoes, and drive on both axles. All types are fitted with 28.5mm diameter wheels (rolling diameter over tread).

Unfortunately we have had to de-list the smallest 160-0010 71.7mm short wheelbase power truck (datasheet) - these have not been available from the manufacturers for nearly five years, and our own stocks are now also totally exhausted. Any existing customers with 71.7mm units who wish to repair/refurbish them should note that we do hold spare wheelsets for this block.

Medium - 84mm wheelbase (from USA Trains NW2 and S4 locomotives)
Long - 94.5mm wheelbase (from USA Trains GP7, GP9, GP30 and GP38-2 locomotives)

Spare Parts :

We also hold in stock spare wheelsets, pickup sliders and traction tyres for all three sizes of USA Trains 2 axle truck.

Axles may appear similar but are NOT interchangeable between truck types, consequently there are 5 types in all. Please specify exactly which type you require when ordering - both truck size and plain or traction tyred. Alternatively we can usually work out customer needs from the locomotive road name and number. All USA trains spare axles are £12.50 each or £45 for any set of 4.

Pickup sliders are the same part for all 4 wheel blocks - new ones include replacement springs and are £4.50/pair.

Traction Tyres are also common to all three sizes of 4 wheel block, £2.50 each or £9.00 for four. Please note we do NOT recommend stretching these small tyres to fit the larger wheels on the various USA Trains 6 wheel blocks.

Unfortunately spare parts for any of the USA Trains 6 wheel blocks are now basically unobtainable, particularly the larger traction tyres. We have a limited stock of some axle types for the PA block, please enquire.

Spare axles and sliders are in our £5 Shipping band for any combination and quantity, see the purchase page for details. For orders containing traction tyres only, the £3.50 Shipping band applies. All consignments are sent Royal Mail signed for / independent courier depending on weight and value.
