Thanks

Answer Thanks for your question.
Like so many things that seem simple, the answer to your question depends. As much as it seems that all railroad rails are the same, there are a range of sizes, all of them slightly different. Rails are basically characterized by the weight of a yard length of that rail. There are other ways to characterize them, but for rail vehicular applications, this is the common method. Size can range from 115 lbs(per linear yard) for lighter weight rail, to over 140 lbs heavy rail. Height from bottom plane to the top of an unground rail will range from 6 1/4" to 7 5/16" for the foregoing rail sizes.
So there you have it. I hope this is useful to you.
