It's not a damn moped!
I found confirmation (of a sort) on the Eagle Games site that a "Rails of the UK" board is coming out...
There doesn't seem to be any update on this information in a long while. It would be interesting to see if they do in fact bring a copy to GenCon next week. I'm also really interested to hear when Rails of Europe will be reprinted.
Hopefully someone going to GenCon can bug the Eagle games guys about RRT and RoE.
