The light rail underframe front end structure comprises a traction beam arranged on a floor and a buffer beam arranged behind the traction beam, a buffer beam cover plate is arranged on the buffer beam, the light rail underframe front end structure further comprises underframe edge beams arranged on the two sides of the floor, the buffer beam cover plate extends forwards to the position below the traction beam, and the buffer beam cover plate extends forwards to the position below the traction beam. Cowcatcher mounting plates extending towards the two sides of the traction beam are arranged at the front end of the buffer beam cover plate; a cowcatcher is arranged on the cowcatcher mounting plate, and the upper portion of the cowcatcher is connected with the cowcatcher mounting plate through an anti-disengaging structure. The anti-disengaging structure comprises a T-shaped mounting plate and anti-disengaging pressing plates arranged on the two sides of the T-shaped mounting plate. One end of the anti-drop pressing plate is connected with the T-shaped mounting plate, and the other end of the anti-drop pressing plate is clamped above the cowcatcher mounting plate; an anti-creeper installation structure is further arranged in front of the traction beam, and an opening and closing mechanism installation assembly is arranged on the anti-creeper installation structure and used for installing an opening and closing mechanism. According to the invention, the space utilization rate is improved, and the anti-falling mounting seat is arranged, so that the operation safety is improved.
