| Highland Railway 0-4-4T Drummond Passenger Tank |
I decided to build my latest project, a HR Passenger Tank, without the aid of a kit although I was aware when I commenced the project that there were two kits available for the engine... I didn't think that either would be of much help. Laurie Griffin's lost wax castings for this particular engine once again are proving to be indispensable however. I began construction at the end of February and these pictures chart my progress. The engine is up and running and will have a test run under club conditions on the CDOGG layout at the weekend.

I've shorted out the wheels on the right hand side of the engine and rigged up wire pick-ups bearing on the top of the left hand side driving wheels, the pick-ups should disappear nicely into the front splashers and side tanks.
The n/s pick-ups are mounted on copper clad insulation board from where a wire leads back indirectly to the motor terminal. The motor gearbox is from ABCGears, it's a Mini 7S with an M1824 motor which will have to run without a flywheel as there is insufficient room for one. It's not the ideal motor-gearbox configuration, though as I had it in stock, it'll have to do.

I added extensions to the LGM white metal bogie side casting for this engine from 0.4 n/s sheet, the rear guard irons are attached to these...mixed solder and glue construction. The centre hole is for the pivot which at the moment is un-sprung though I'm thinking about this. Wheels run in 1/8" bearings without compensation.
