Twenty minutes ago, I had never heard of rail bikes. Now I must have one. Maker of this rail bike and Velospace member Stinky Pete writes, "This is what happnes when a person works nights with too much time to think." I should start working nights if it produces marvels like this.

Railroad companies can be real killjoys.
Some bikes have been built with flanges on the rims, some "bikes" have even been built with four wheels and the rider in the centre (there was a name for these, but I don't recall it). However fewer have been built with proper conical rims. It's the conical "tyres" that keep rolling stock centred on the tracks, not the flanges. And certainly not a fixed plate.
