How much does a railroad tie weigh?

A railroad tie weighs between 145 and 200 pounds, depending on the condition or grade of the tie. This weight is based upon the most common size of railroad tie in use today, according to the Railway Tie Association.

The most common size of railroad tie is 9 inches wide, 7 inches tall and 8 1/2 feet long. The other common length is 9 feet.
