TESTING CONCRETE TIES

After commenting on the resons for increased interest in concrete ties in the U.S., the author describes the feasibility study undertaken by Chessie System to investigate the technical and economic aspects of such substitution. Experience elsewhere and the economics of such substitution were first examined. Laboratory tests were then made of selected ties. Finally three field tests were made. There was evidence of higher lateral resistance for the concrete-tie track. The reduced resistance to buckling after tamping is discussed, and the advantage of ballast compactors must be studied.
