Ger, I spend my day around railroad stuff. I have been thinking about your railbike. I spend a lot of time with our production engineers, and one of the guys and I teach classes. He was redoing our truck building shop. The new stands had just come out of paint and I looked at the wheels and asked where he got them. I saw a the possibilities. If I had a place to do use it, I would build one. Kind of a modified go kart frame. With flanged wheels you can go pretty fast.
