A low height and long span girder for a railway is provided to reduce deflection and vibration by fixing reinforcing units to the upper part of a holding unit. A low height and long span girder for a railway comprises main beams(10A,10B), rail support units(20), and a holding unit. The rail support units are fixed at predetermined intervals between the main beams within the outermost section(A) and the intermediate section(B). The holding unit is placed between the lower sides of the main beams in the center section(C). Reinforcing units are fixed to the upper part of the holding unit to form three support frames. A stiffener(50) is fixed between the main beam and the reinforcing unit. |
