The Wickham trolley moves!

I managed to find 4 bearing in Brian's 'box of useful bits' which allowed me to make some progress on the paxolin 'chassis'. In order to be able to remove the wheels I have found some bearings which fit into some U channel. The Polish motor has a 1mm shaft which I sleeved with a 1.5mm brass tube.
The little runner wagon has wheels shorted out on one side so while I've fitted pick-ups on both sides with pickups I may well just try and short out the wheels on the opposite side on the main trolley.
At the moment the motor is just wired to the wheels, ultimately there will be a DCC chip involved which I suspect I'll have to mount under the roof. In order to test things out I've wired a DCC chip to power the track as this allows me to limit the voltage to the 4 volts or so the motor is designed for.
With the body of the trolley in place you can see that most of the mechanism will be hidden from view. With a little bit of weight it crawls along and is actually quite controllable apart from the usual problems with stalling with the pickups. Once the unit is on DCC and the voltage is higher and constant I think things should be better. I can see I'm also going to have to weight things carefully as the single driven axle has a tendency to slip.
All I can add is that it is fa*&ingly small!
