ADHESIVES IN RAIL-JOINT ASSEMBLIES

Railways are testing the use of adhesives in rigidifying rail-joints to eliminate rail-end batter and reduce maintenance. Preliminary tests showed that joints so rendered inflexible ensured a smooth-running continuous rail likely to add 10 to 15 years to the life of existing track. The glued joints also reduced maintenance by eliminating the expansion and contraction in ordinary joints. A 300,000-lb resistance to slipping is reported with Bondarc applied to clean, sand-blasted fishing surfaces, and by butt-glueing the rail-ends additionally a further 40,000 lb is obtained. As no fishbold tension in excess of 20,000 lb was needed it was not found necessary to use high-strength bolts. Tests were conducted in Northeast Canada to ascertain the effects of a combination of the lowest temperatures and heavy traffic on glued joints.
