ALLOY STEEL RAIL (CHROME-VANADIUM OR "CV")

The CV rail was laid in October 1953, in connection with regular rail renewals. The location was selected because it was one where moderate shelling had developed in the previous 131-lb. rail over a period of about 11 years. A total of 47 CV rails were laid--16 on the low side and 31 on the high side of the curve. Measurements of gauge superelevation, ordinates and rail head wear were made. A final inspection of CV rail was made on October 29, 1959, at which time 30 CV rails remained in track. There was no indication of shelling, although, some flaking was noted on the CV rail, and there was no indication of rail and defects. The results of this test have shown the CV alloy steel of the composition used to be unreliable. Its good wearing qualities and superior resistance to shelling are over-shadowed by its poor resistance to impact.
