RUBBER TIE PADS UNDER CROSSING FROGS

The purpose of this test was to determine if rail abrasion pads applied between tie plates and crossing frogs and anchor seal pads applied between timber and tie plates in railroad crossings would result in reduction of noise, improved riding conditons, reduced maintenance, and increased life of frogs and timber foundations. The test locations are in heavy-tonnage tracks and in high speed territory. The frogs at Valparaiso developed considerable batter and tread wear after a very short period in track. Chipping and cracking of the castings was observed within six months. The pads were in long enough to determine that they did not have sufficient rigidity to withstand the large forces to which they were subjected. Both anchor seal and rail abrasion pads were deformed and torn. The crossings in both tracks at Orrville have given satisfactory service. There has been little difference in maintenance required for the crossings with and without pads. There was no significant reduction in noise to be realized from the use of pads. The use of tie pads will prevent tie plate penetration into crossing timbers.
