Abstract
A railway tie pad is provided with studs that are either offset from opposed positions from each other, on opposite sides of the pad; or are of differing heights. Pads with these features are capable of being more efficient in isolating ties and rails from shock loading, and in accommodating varying loads with differing cushioning characteristics.
