Move onto now and I'm thinking about the Kotanga Valley Posthole Mining Co. and how they need a loco for hauling mine tippers and side dump wagons and the like about. On the earlier layout I was going to build a Ewings system monorail for the mining Co., but common sense has prevailed and I'm going to use 1&1/2 inch gauge Lego and Lego clone/compatible track instead of which I have a considerable amount. I trial fitted a 4.5 volt Lego mech under Kotanga Works No:1 to see if it will fit and it looks like it will without any problems.

The wheel arrangement isn't quite right and the leading wheel set should be a round flywheel crank thing on a countershaft, but I'm not that bothered over it. Visually it looks close enough to my Woolworths eyesight.
Old mech and the new.

A look underneath.

An immediate problem is that there's nowhere to fit any batteries as the cylindrical cooling tank is full of something heavy firmly sealed in by a wad of two part acrylic compound. Remember this loco used to pick up current from the rails by virtue of its ancient Triang mech.
I'm considering making one of those peaked roof tool wagons to more or less permanently hitch behind this loco and that can carry the batteries, electrickery speed control & etc.
