Description
This kit is intended to replace the mechanism of the RTR J72 by Palitoy Mainline (later Bachmann) and to improve the excellent moulded body. It includes a complete etched chassis that fits directly to the original mechanism mounts, a wooden plug to replace the part of the boiler bottom that forms part of the Mainline chassis, a fold-up cab interior to eliminate unseemly daylight and etched bufferbeam overlays. A UC04o handbrake column is also included.
The chassis can be built for 00 or EM/P4 gauges, rigid or with suspension, and will take a wide range of drive trains. The simplest & cheapest is a Mashima MH1024 flat-can motor, a MT161 motor mount and Romford 40:1 gears. An alternative is the Comet GB5/15 multi-stage gearbox. The recommended wheels for 00/EM are Markits 4’0″ 12 spoke (order code WH200 with Markits crankpins and axles.
If you wish to fit a suspension system, any sprung/compensated system designed to use standard 6mm x 7mm hornguide cut-outs can be used.
Please note this product no longer includes sprung buffers, as the prototype had a choice of three: 4904 parallel (first 20 built); 4911 tapered (all other NER/LNER builds); or 4909 LNER Group Standard (BR batch, plus fitted at random to earlier locos from 1931 onwards).
