For those interested, I voted against this motion because I thought that it was pretty clearly overdoing it -- a 'world rail' forum for train travel outside both the US and Europe seemed destined to fail, and a non-Amtrak US commuter rail forum seemed a bit unlikely to generate sufficient traffic to be useful as well.
I'm honestly not sure how a rail forum would work out, it might or might not, but (3) new rail forums was more than I was willing to support.
