DECAUVILLE 0-6-0T NG BUILD IN 3.5” GAUGE

Part one by Julius de Waal

Some time back Julius de Waal produced a design on MEWS for a Decauville 0-4-0 in 45mm gauge. That has proved popular with MEWS readers. Now he has produced drawings for the 0-6-0 Decauville in larger scales for 3.5” and 2.5” gauge.

Decauville was a pioneer of industrial railways in France, successfully using portable track from 1875, initially of 400mm gauge, but later 500mm and 600mm. The company exported engines, track and rolling stock to many countries, for use in mining, quarrying, construction, farming especially can fields and mountain railways. The Decauville system was also the one used by the French and British military in World War I.

In 1878 Decauville built a railway system at the Exposition Universelle of 1878 in Paris. This Jardin d’Acclimatation railway was built in the Bois de Boulogne and was the first passenger railway in France. It exists to this day, drawn by electric locomotives. Return fare from Porte Maillot to the garden is €2.90.

A number of examples of Decauville locos have survived, including 0-6-0s, many of them in running order (see photo top of page running at Amberley).

The model is drawn on A1 sheets in Solid Works. It should be possible to build without the use of castings. Cylinders might be fabricated or adapted from castings for another design. Wheels might be machined, or CNC cut by laser or water jet. Indeed, a great deal of this model could be made making use of water/laser cut parts.

The boiler is a new design, and as with all new designs builders should check with their boiler inspector before starting work to make sure that he has no problem with the design, build method chosen and operating parameters.

This time we include half the drawings for the 3.5” gauge version. These can be downloaded for MEWS readers’ personal use, and can be viewed full size (or larger!) in Adobe Reader. CLICK ON DRAWINGS TO DOWNLOAD. FOR PERSONAL USE ONLY.
