SERVICE TESTS ON CROSSINGS

Service tests of crossings were reported. A shot peened casting installed in a test corner of a crossing showed that the depth hardened running surfaces had not worn down to fit the average wheel tread three months after installation. An inspection of four crossings using manganese insert and solid manganese supported on structural steel substructure and longitudinal timbers showed that all crossings were slightly out of line in the east and west direction, and the movement had been with the traffic on the north and south tracks. The crossings were in good condition except for some batter on the castings. A new installation of a solid manganese crossing on a structural steel T-beam substructure of revised design was described. Continuing tests of crossing frog bolt tension was discussed. The installation of a test crossing on a main line location where high speed operation prevails at Warsaw, Indiana was described.
