Abstract
A direct fixation track rail fastener includes a first clip shoulder and a second clip shoulder each having a clip tunnel formed therein. Each clip tunnel is formed in part by a plurality of clip contact faces defining a first prong contact line and a second prong contact line for a prong of a rail clip. The configuration of multiple line contacts prevents undesired displacement of a rail clip during service.
