R-46 problems from the beginning to the present day

The R-46 began when the first cracked R-46 Rockwell HPT2 truck was discovered in March of 1977, just a few years after the R-46s appeared on the subway, after a transom arm cracked off its parent-side frame casing, causing the traction motor to fall onto an axle. The lightweight trucks operated under stress forces three times greater than what they were designed to handle. Filters were installed in test instrumentation when Pullman Standard, the builder, tested the trucks in 1973, and these filters were used improperly, masking stress forces.
