THE ALLOWABLE LIMIT OF LATERAL PRESSURE ON RAILWAY TRACK

Three kinds of tests were made. The first test measured the strength of dog-spikes for sleepers sampled on the test sections, the second one measured the pressure on some dog-spikes under lateral pressure and wheel load upon rail exerted by a lateral pressure test car, and the third one measured the shift of dog-spikes on all sleepers of test sections after a loading run of the lateral pressure test car. The lateral pressure test car was a freight car with two axle bogie, which had a special axle below its center which can exert both lateral pressure and wheel load of variable amount by means of compressed air. Test results showed that considering the distribution of the lateral pressure caused by rolling stock and that of the strength of dog-spike, the limit of lateral force was established so that the pressure of 1% of dog-spikes may amount to their proportionality limit.
