ABSTRACT = {The present article focuses on the evaluation of the dynamic behaviour of a centenary steel arch 
bridge, located in Portugal, under light railway traffic loads. The work aims to assess the dynamic 
behaviour of the bridge subjected to an alternative type of railway vehicle, more specifically, a 
typical underground vehicle that is currently in service in the Lisbon Metro. The dynamic response 
of the system has been evaluated using two distinct methodologies, namely a moving loads model 
and a vehicle-bridge interaction model. To achieve this goal, finite element (FE) models from both 
the bridge and the vehicle have been developed and a comprehensive study has been carried to 
evaluate the influence of distinct factors in the dynamic response of the bridge-train system, 
namely the methodology used to assess the dynamic response, the location of the response 
reference point in the deck, the train speed and the vehicle configuration (single or double vehicle). 
Moreover, both the traffic safety, passenger comfort and pedestrian comfort have also been 
evaluated using normative criteria based on acceleration responses. The results shown that the 
normative limits related to traffic safety and passenger comfort were never exceeded in any 
condition analysed in the study. However, the pedestrian comfort was jeopardized when the train 
speed exceeded 20 km/h.},
