I have just got a book called "The Stronach Dutton Roadrail System of Traction", published by the Narrow Gauge Railway Society, ISBN978-0-9554326-9-9.
For anyone unfamiliar with the system it used a rail guided rubber tyred tractor to pull trains on lightweight track. All of the disadvantages and advantages of both road and rail in one system, no wonder it never caught on.
There are a few bits and pieces about the Stronach Dutton system on the web - this has photos of the various tractors, including a half track! http://www.mprints.co.uk
- click on the Stronach-Dutton link.
It was only ever built to 2 foot and 2 foot 6 inch gauge, but a minimum gauge version is a very tempting prospect, especially as I have an old unbuilt Thomas Flyer kit that needs putting together. It was going to be a wreck in the background but.......
More distraction, will my GLS30 diesel ever get finished?
