Railway bridge with the warren type truss structure in the Sumatera region is an infrastructure has existed since the Dutch colonial era. Bridge is used as a mode transportation for natural resources of coal. The construction of railway bridge must always be monitored and evaluated for the feasibility of the structure, especially for earthquake load. This is due to change the latest of earthquake hazard maps and regulations regarding earthquake load. The research used SNI 2833:2016 regulations, about bridge planning for earthquake load and 2017 earthquake hazard maps, by modelling the 42 meter warren type of truss structure using SAP2000 V.21 software. The results of the research indicate that, the largest of mode shape value occurs UZ point with the 6 mode number of 0,82536 displacement unit and a period value of 0,075276 second. The largest of period (T) value occurs in 1 mode number of 0,37002 second. The maximum displacement occurs U3 point at the joint 25 of 36,437377 mm opposites the axis. The value of displacement in the direction of U3 is smaller than the value of allowed deflection of 52,5 mm. Then, at the stress control, there are 13 frames that have overstressed and the maximum stressed of frame occurs on the pressure frame, the IWF126.96.36.199 frame has the Pu value of 22,462 tons with a nominal compressive capacity (Pn) of 12,612 tons. Based on the 3 reviews, it can be concluded that, the bridge structure requires structural reinforcement on cross girder 1 (IWF1100.400.16.28), 2(IWF1100.400.16.28) and 7(IWF1100.400.16.28) frames and on wind bracing 13 to 22 (IWF188.8.131.52) frames
