Nigel Lawton 20hp bow-framed Simplex

Nigel Lawton was demonstrating a 7mm:ft scale version of his 20hp bow-framed Simplex kit at ExpoNG 2008. Originally developed for OO9, the etch artwork for the new loco has been (literally) scaled up with some changes the drive system allowed by the larger size.

While the OO9 loco relies on a friction drive for the reduction gearing, the 7mm kit has a more conventional belt drive and the further modification of a working radiator fan. Currently this is linked to the direction and speed of the Simplex but Nigel has some ideas to keep a constant fan operation even on DC power. There should also be room to fit a small DCC chip inside the engine cowling.

The kit should be available late 2008 or early 2009 and can be built to 14mm and 16.5mm gauges.
