On the advice of the honourable member of Litlington I took a look at the website of KK Produkcja Mikroantriebe in Poland. http://www.shop.kkpmo.com/ and purchased a frankly tiny motor and gearbox. The motor is obviously one from a phone and is 6mm in diameter the 80:1 gearbox takes the overall length of the unit to a massive 22mm! The unit was tested at takes about 4v to reach maximium speed, this shouldn't be a problem as I can limit the voltage using the DCC decoder which I'm going to have to squeeze in somewhere.

I've had to trim the 1mm axle down to length a bit and have also realised that I have a problem as the foot boards are very close together to fit P4 wheels between. I'm certainly going to have to do something pretty serious with the width of the N gauge wheels provided in the kit as with them at the thickness they currently are I'm never going to be able to fit them in.

I'm quite pleased with how little the unit is going to project into the 'cab'. Bear in mind that there is a seat going across this I thick a small pile of tarpaulin and the gangers' lunch should be able to hide it.

Put together with the trolley I think this has the potential to be a small but eye-catching addition to my layouts stock.

I expect the next step is to make some kind of paxoline base as a chassis and then work out how I'm going to get the wheels to fit on the 1mm shaft. I beginning to think that taking the tyres off the wheels, turning them down and then making a new tufnol centre may be the way to go.
