Abstract
A rail pad can have a major face forming a railseat portion on which a foot of a railway rail sits when the pad is in use, the railseat portion having opposite side edges to at least part of each of which a respective upstanding portion of the pad can be connected, wherein the pad does not have any part which extends laterally from the railseat portion in a same plane as the railseat portion. The respective upstanding portion can be connected to a projection of the rail pad which extends laterally from the respective upstanding portion such that the projection can be vertically spaced from, and does not overhang, the railseat portion, the projection spaced from ends of the respective upstanding portion such that the projection can be configured to interlock with a corresponding opening in a front part of one of the railway rail clip anchoring devices.
