EVALUATION OF THE STABILITY OF THE M130 AND D1G CONTAINER CARS

The railroads have been experiencing difficulties with 100-ton cars having a high center of gravity. The results of the tests showed that the M130 Container Car and the simulated D1G container car were both sensitive in roll to track-induced inputs in the as received condition with standard D-3 springs. At 22 mph, the car roll amplitude reached 7.5 degrees and wheel lifts of e inches were retested. The rocking action was reduced substantially but 2 -in wheel lifts occurred within 1 mph of the critical speed of 22 mph. The addition of 8 Stucki HS-6 snubbers to the D-4 spring group eliminated wheel lifts up to 22.5 mph. The dynamic roll action of this 350,000 lb. car produced excessive track degradation in the as received condition. The hydraulic snubbers and D-4 spring modification reduced this track degradation by a factor of 4 to 1.
