Hi everyone,
this is my last locomotive creation, it’s a diesel switcher 0-4-0 with a particular rear cams drive system.
This locomotive was ordered by the Ministry of Defence in 1941 and was designed and built by Andrew Barclay, Sons & Co.Ltd..
In October 1992, was restored to its original number WD42 and named "OVERLORD" as part of the 50th Anniversary celebrations of the D-Day Landings
The real challenge was to build a telescopic piston, because the cam and wheel have different distances.
I’ve cut a flex cable then inserted in a rigid hose. This is the sequence of the piston during the rotation of 360 degrees.
Another challenge was to fit the battery and the engine in the shape maintaining compliance with the original blueprint.
This locomotive has a transmission system with a worm screw to reduce the speed to a very low ratio.
The low speed of the locomotive, in favor of the power, has made possible to avoid the use of an infrared receiver using a simple on-off-on switch.
As always in my locomotives, there are lights, a single led on the front and on the rear.
For the project I have to thank Toastie again for providing the medium grooved wheels with the O-rings!
Soon I will post my complete project named “Coal District” …keep on watching!
