Nowadays light rail transit (LRT) system is more desired to use due to improvement of travel option, sustainability and facilitating swift mobility in urban area. Hence, structural stability and safety of these public transportation systems against the seismic occurrences is indispensable. Since, these structures cannot be considered as conventional frames due to complex architectural design, therefore in order to design for lateral resistance system, it is vital to focus meticulously on reliable seismic design codes and structural rehabilitation techniques. In the present paper, the LRT station located in Malaysia is considered and seismic response of train station with supplementary viscous damper devices is evaluated. So, LRT station is modeled using finite element simulation. The developed model subjected to multi support excitation and time history analysis was considered. The seismic response assessment is reported in terms of structural displacements as well as base shear. The result indicated that implementing viscous dampers have a significant decrease in response of structure during earthquake excitation. Maximum value of displacement and base shear are declined by approximately 40% and 60 % respectively in model equipped with dampers compared with bare model. The efficiency of implementing damper device in seismic response of LRT structure has been proved.
