1. A track chain member comprising:
a shoe member defining a track chain traveling direction and a lateral direction perpendicular to the track chain traveling direction defining a first lateral end and a second lateral end; and
a first track pad member extending from the shoe member including a first lug member extending from the shoe member in a first direction parallel to the track chain traveling direction, a second lug member and a third lug member both extending from the shoe member in a second direction opposite of the first direction; wherein
the first, the second and the third lug members define a Y-shaped configuration including a single continuous planar rail surface, and the track chain member further includes a first rib disposed nearest the first lug member along the track chain traveling direction extending from the first track pad member along the lateral direction substantially to the first lateral end of the shoe member, the first rib defining a first concave radial portion, and a second rib disposed nearest the second lug member along the track chain traveling direction extending from the first track pad member along the lateral direction substantially to the first lateral end of the shoe member.
