The invention relates to a simulation driving system of trains, which comprises a master control device, a data collecting and output device and a vision simulation device, wherein, the collecting and output device receives and transmits the input data of simulation driving to the master control device; the master control device produces simulation data according to the input data of stimulation driving and sends the simulation data to the vision simulation device to set up simulation scenes of trains when running. The simulation driving system of trains can be used for training master operation skills of train drivers and drivers of city light rail or underground during transportation operation process so as to ensure that the workers have relatively high professional levels and relatively high ability for handling emergencies.
