I have been interested in this concept for quite a while. It's not a new idea as quite a lot of 4wheel trams had stear able wheels but they were connected to opposit corners of the single axle bogie. If you put the question into Google they have a lot of pictures. And diagrams. A good few years ago a 7 1/4 tram was described by the builder had used quite a simple way of doing this. As I recollect it was something like a steam loco bogie and you used light springs to centre the bogie but there was a enough movement to allow the wheels to turn about 5 degrees. Also Hornby Railways used a simple design to allow long wheel base wagon to go round tight curves on 16 mm gauge track.

Thanks Mike the amount of stuff on Google is mind boggling only taken a quick look up to now. I imagine a 5 degree swivel would be enough but the mathematics for working this out are beyond me.

Sorry this subject has got 2 threads it happened when I went to edit the original perhaps as soon as an admin spots this they can be merged?
