groove girder rail
i am analyzing a bridge with rails on it from the 1920s.  the rails sit on i-beams, but i don't know anything about the rail strengths or physical properties.  can anyone point me in the right direction as far as a 7"-128# groove girder rail?

slideruleera has lots of great resources on his/her (willing to bet his given the apparent seniority of the poster) and it would be a great place to start...
