SKU: TBWKIT32 Category:


The Trefor breaker wagon model kit is based on two foot gauge wagons used by the Trefor Quarries (formerly “Trevor”) in the Lleyn Peninsula of North Wales to transport dressed granite paving setts from the cutting sheds on the quarry levels up on the mountain side, down a roped worked incline and then locomotive hauled to a coastal jetty for hand loading into ships. The “missing” side facilitated easy hand loading and stacking of the setts.

In 1914 when the market for these setts declined, the quarry switched to the production of crushed granite road stone. The breaker wagons were hand loaded with boulders and small pieces of stone at the work face and then taken down an incline to the lowest quarry level. Here they were tipped into a new stone “mill” where the boulders were crushed into road stone. This stone was then taken to an improved jetty complete with wagon tipplers by new “mill wagons”.

The quarry was rail operated between 1850 and 1962 and a number of locomotives were used including De-Wintons and latterly Hunslet diesels. So there are plenty of modelling possibilities.

This SM32 kit features:

Easy to assemble chassis

The model features characteristic curly spoke wheels and outside pedestal bearings. The chassis parts are cut from premium quality MDF board which slot together to give a nice “square” chassis ensuring good running characteristics with a greatly reduced risk of derailment.

Laser Cut Bodywork

The wagon body is cut from premium quality poplar plywood which may be painted, stained or simply left bare. Both sides of the body work have engraved plank details so that wagon looks good even if no load is being carried.

3D Printed Sintered Nylon Detailing

The kit includes several detail parts 3D printed in SLS nylon. These include corner plates, floor support brackets and the distinctive end stanchions. They come pre-coloured in a satin “charcoal black” finish.

Bell Mouth Center Couplers

Also included is a new design of “bell mouth” coupler,  again 3D printed in SLS engineering grade nylon. These couplers can be used in a prototypical manner with the provided link and pins or in a more traditional “garden railway” way by slipping the supplied coupling chain over the top pin and coupling to the more traditional centre buffers.

Paint and glue not included
