  • Railway tie collar
    Patent number: 4121766
    Abstract: A track supporting railway tie collar includes an upper receptacle for slidably and loosely receiving an end portion of a cross tie and a lower enlarged portion supported in the ballast beneath the track structure. The collar serves to transfer the weight of the train directly to the ground, rather than through the tie, thereby greatly prolonging the life of the tie and minimizing track maintenance.
