The invention relates to a layout method and structure suitable for a subway operation engineering vehicle power system, a vehicle frame is used as a carrier, and all parts of the power system are fixed on the vehicle frame; and an internal combustion engine introduces power from the upper part of the frame to the lower part of the frame through the hydraulic torque converter to ensure the workingangle of the transmission shaft; a hydraulic power generation device is arranged on the frame, power of the internal combustion engine is transmitted to the reduction gearbox through the rear end ofthe hydraulic torque converter, the output rotating speed is adjusted to the required range of the hydraulic power generation device during operation walking, and power generation is achieved throughthe hydraulic power generation device. Under the working condition of high-speed running, the clutch in front of the reduction gearbox disconnects the hydraulic power generation device, the power of the hydraulic torque converter directly reaches a vehicle wheel set, and the high-speed running power requirement is met; and, under the working condition, the clutch is closed, and the requirements for low-speed walking and power utilization operation are met. According to the invention, an integrated modular form of a hydraulic driving and driving generator transmission system is adopted for layout of a subway operation engineering vehicle power system, the integration level and the modularization are high, and the maintenance is convenient and extensible.
