Abstract We numerically investigate the train-induced transient pressure on platform screen doors (PSDs) of an island-type in a subway station according to real scenarios and full-scale simulation enhance understanding design safe operation trains. Two typical cases, namely, non-stop chasing were examined, with train’s speed variation well simulated throughout both cases. In case, train passes ...
