RUNNING APPARATUS AND TESTING APPARATUS
A running apparatus includes a rail, a bogie, and a control unit. The rail has a linear segment provided on a floor part, which is parallel to the horizontal plane, at least one curved segment connected to at least one end of the linear segment and curved upward from the linear segment, and an upright segment connected to the upper end of the curved segment and extending upward. The bogie includes a running unit capable of running on the rail. The control unit controls the running unit so that the bogie can run at a certain speed on the linear segment.

METHOD FOR MONITORING TRANSPORT VEHICLE AND MAINTENANCE THEREOF
A method for monitoring a transport vehicle is provided. The method includes the operations as follows. A transport vehicle is scanned by a monitor during the transport vehicle is operated on a rail to acquire a vehicle pattern of the transport vehicle. The vehicle pattern of the transport vehicle is analyzed. An abnormal transport vehicle is determined based on the vehicle pattern. The monitor is placed nearby the rail. A method for transport vehicle maintenance is also provided.
VEHICLE BODY CONTOUR-BASED DERAILMENT DETECTION METHOD FOR RAIL VEHICLE
A vehicle body contour-based derailment detection method for a rail vehicle, including: measuring distances between measuring points and rails through a range finder mounted on an underframe of a vehicle body, and calculating a transverse displacement of the current vehicle body in a vehicle body coordinate system; measuring an inclination angle of the current vehicle body in the vehicle body coordinate system through an inclination sensor on the vehicle body; with reference to a size of the vehicle body and distribution positions of the measuring points, as well as the transverse displacement of the current vehicle body in the vehicle body coordinate system and the inclination angle of the vehicle body in the vehicle body coordinate system, obtaining a dynamic outer contour of the vehicle body in the vehicle body coordinate system and converting it into a dynamic outer contour in the rail coordinate system.

Fuel system test apparatus and method
A method that includes coupling an external, removable fuel pressurization system to a fuel system of a vehicle while the vehicle remains in a confined space. The fuel system of the vehicle is pressurized with the fuel pressurization system while the vehicle remains in the confined space and without activating an engine of the vehicle. Decay of pressure of the fuel system is monitored following pressurization of the fuel system, and one or more of a leak, or a replaceable component, of the fuel system of the vehicle is detected based on at least in part on the decay of pressure that are monitored.
