The invention discloses a railway track engineering vehicle operation neutral section passing control method and a control system, and the control system comprises ground magnetic inductors and disconnection and connection signboards which are installed at the two sides of a line. The pantograph, the transformer, the four-quadrant rectifier, the traction converter, the auxiliary converter, the traction motor, the auxiliary power source, the middle direct-current link and the magnetic inductor detection device are installed on the rail engineering vehicle, and the controller is used for controlling the rail engineering vehicle. And the power supply of the intermediate direct current link is gradually switched from the four-quadrant rectifier to the auxiliary power source, and is gradually switched back to the four-quadrant rectifier from the auxiliary power source when the neutral section is recovered. The controller can control the back-and-forth seamless switching of the contact network power supply and the auxiliary power supply under the vehicle operation neutral section passing working condition, so that the whole vehicle auxiliary equipment is not powered off, the vehicle impact is reduced, the operation interruption is avoided, and the pantograph-catenary safety is ensured.
