An assembly monitors exterior regions of a rail vehicle. In the region of the front side of the rail vehicle, a driver's cab is arranged, which driver's cab has a driver's cab field of view in a first direction of travel. A first lateral region has a first camera system oriented in the direction of travel, which optically captures an angular range along the first lateral region as a first lateral field of view. A second lateral region has a second camera system oriented in the direction of travel, which captures an angular range along the second lateral region as a second lateral field of view. The first and second camera systems are connected to a display device so that image series of the lateral fields of view in the first direction of travel are displayed to the traction vehicle driver in addition to the drivers cab field of view.
