I have a couple of the IP chassis in 2 of my Steam Trams. I can manage a 2D drawing for you to scale if it helps. I use MacDraft PE on my iMac, I doubt the files would be compatible for you but at least they will be scale size.Don't worry, I'm still enjoying it at the moment and it's helping to sharpen some skills that have started to dull since I changed jobs. I'll only start to charge when I start to loose patience with it
I'd thought the IP gearbox might be a good choice too. I had worried that maybe it wouldn't be butch enough but in reality it shouldn't have too much work to do. I think I can make a pretty good representation of it from the measurements on the website. Once the floor is in I'll have a go at trying to get it in there.
Shame it closed as it may have been a good line to keep restored, however as there was in effect no Station at the Junction (Radley being closest to the Junction where branch trains worked from/to if a shuttle) it would have been another line from somewhere to nowhere.We moved to Abingdon in April 1976, almost 46 years ago now, so still newcomers. When we moved here the old GWR Abingdon branch line was still in use for freight, passenger workings had ceased some years before. Apart from the occasional coal delivery to the coal merchant who still occupied the old sidings area, the only freight was the car transporter trains taking the new MGs to the docks for export. The MGs were brought from the factory, on the other side of town, by road car transporter. They were then driven off of those and straight onto the car trains. If I remember correctly, the trains were hauled by Class 31 diesels in BR blue livery. This traffic went on pretty much up until the time the MG factory closed. A sad loss for the town of Abingdon and the Nation as a whole. With the loss of the MG car transportation, there was no further use for the branch line and it was lifted.
