I'm biased, so take everything I say with a grain of salt :)
I'm not sure there is a rails really and I think that's somewhat by design. Compojure is probably the most famous Clojure web lib, but it's not a framework per se. It's at a level below web-frameworks as most people think of them and Noir is actually built on top of it.
If you're just wondering in terms of having an active community, I believe Noir is currently the most trafficked complete package, but Compojure itself draws a lot of discussion :)
