Something that will make you all laugh.... it made me cry... I have made my first scratch built truck - well it's a people work van - built on the chassis of a Nequida oil tanker. Painstakingly made all the parts on my CNC router, glued and painted it. It has 2 Moving buggies each with 1 axle. So I added a centre set of wheels intending to drive these with motor and gearbox. Took it out to the track for a test push... First time that have the concept of wheels going round R1 curves! It jammed at first curve and I discovered that the centre wheels had to move side to side 15mm! Not possible with the motor fixed inside the carriage... Back to the drawing board...
How about fixing the motor to a sliding plate within the car which is attached to the centre wheels and moves acrossie with them?Something that will make you all laugh.... it made me cry...

Pictures!!
Got phone back so here's some pics. Now removed centre wheels as you can see! And cut chassis and moved wheels much closer together... I now have a plan! Somebody on here posted some pics of really small cheap gearboxes that went on the wheel axle? I lost the thread and can't find them on ebay or amazon...Pictures!!
Thanks Phil - i've seen them. The ones I have seen are in a small clear plastic housing and I think the axle passed through it. I bought a couple of blue rectangular gear boxes with motor inside with an axle incorporated with 3mm shaft but they were not good (cost about £3). Slow speed was non existent, they just started after about 2.5v and abruptly and didn't seem as if they would last, lot of noise and vibration. I took them to bits and there were no bearings just moulded plastic. Fun this isn't it!
Too substantial for my redesigned railway. The building with the canopy will be on the track two platform and will serve as a waiting room and a P-way store.Can you get another canopy?
Perhaps move the ticket office from the Station Master's house?
Make a substantial station building complex.
Yes it looks fine to me too

It is if you make the motor and axle one unit that is sprung down for adhesion and the whole unit can slide sideways Getting the springing right is the challenge.Not possible with the motor fixed inside the carriage... Back to the drawing board...

Made my own blue.Not happy with the color. Way too blue. The color on the lid was perfect though. Needs more white, I will make my own color.

If you have time, would you mind supplying the measurements for the body work, height, width, length and so on, rather struck on it's appearance, and with time and materials to hand, may have a crack at building something similar, with Bluetooth control and Li-Po batteries.
