The invention discloses an urban rail transit elastic split fastener system with a retaining shoulder. An iron base plate and an under-plate base plate apply downward buckling pressure through screw spikes and are arranged on a sleeper/rail plate with the retaining shoulder. Meanwhile, the transverse baffle and the elastic buckling base plate are buckled and limited on two sides in the sleeper/track plate bearing groove through the iron base plate. An under-rail base plate and a steel rail are respectively arranged on the iron base plate, a right-angled insulation gauge block is arranged on the outer side of the steel rail corresponding to the T-shaped bolt, and the lower portion of the T-shaped bolt is located in a corresponding T-shaped groove of the iron base plate. The omega-shaped elastic strip is pressed by the T-shaped bolt, one end of the omega-shaped elastic strip is buckled on the insulation gauge block for fixing the steel rail, the other end of the omega-shaped elastic strip is buckled on the iron
