BRAKING AND ACCELERATION FORCES ON BRIDGES. BRAKING TESTS ON STRAIGHT TRACK WITH A LONG TRAIN

The tests were designed to establish whether some reduction of peak braking effort might be obtained due to propagation time in a long train. Performed, more expediently on plain line with a train of oil tank wagons, some advantage for long bridges was proved, particularly with loose coupling. The tests serve to explain how, in a long train of 20 wagons, the resultant frictional coefficient falls below the value of 0.15 of the individual wagons. For economy they were performed in a station track at Reichertshofen with full and with shortened train, and with both close and loose coupling.
