RAILchat.Com - Your Railroad Talk Station. For your convenience, we have created four railroad chat rooms: Railfan, Model Railroad, Rail Travel and Anything Rail(default room). This new chat system allows 50 concurrent users to chat simulteneously. Since this is a new feature at TrainWeb, you may need to wait 10 to 30 minutes or longer before another user comes into the chat room. You might want to send e-mail to your friends that are interested in rail and invite them to the RAILchat.com site.
