EFFECT OF UNIT TRAINS ON CONCRETE RAILROAD BRIDGES

Unit trains can have detrimental effects on concrete railroad structures built 50 years ago or more. Foundations can be inadequate and settling may damage elements; many bridges may have inadequate or no steel reinforcement; concretes may not be uniform or have developed internal stresses or be weathered so they are readily damaged; and there can be problems with bearing plates, anchor bolts and other metal components.
