The invention provides a train pipe inspection system and a 25t axle load aluminum alloy coal hopper car system. The train pipe inspection system comprises a strain type pressure sensor, a pressure switch, a control device and an upper computer. The strain type pressure sensor is arranged in an installation space defined by the end wall vertical plate, the supporting plate and the bottom plate. The strain type pressure sensor is communicated with a train pipe of the 25t axle load aluminum alloy coal hopper car. The pressure switch is arranged in the mounting space. The pressure switch is communicated with a train pipe of the 25t axle load aluminum alloy coal hopper car. The pressure switch is used for determining whether to output a trigger signal according to the pressure value of the train pipe. The control device is electrically connected with the strain type pressure sensor and the pressure switch. When the control device receives the trigger signal, the control device detects the current pressure value i
