An embodiment of the invention provides an automatic adjustment method for train operation. The automatic adjustment method comprises the following steps of: 1, modeling a waiting process of passengers before a train enters a station, a getting-on and getting-off process of passengers after the train enters the station and a passenger retention process after the train leaves the station, and establishing a dynamic passenger flow simulator; 2, establishing a mathematical model by taking minimization of the total train delay time and minimization of the total number of passengers detained on a platform as optimization targets and taking train operation grade selection, train station dwell time, train safe operation interval and train detention time as initial constraints; 3, generating an initial train operation scheme according to the predetermined operation data, the real-time passenger flow information and the real-time delay scene of the train; 4, updating the mathematical model according to the deduction time constraint of the deducted train, performing iterative solution on the updated mathematical model, optimizing the initial train operation scheme, and outputting the optimized train operation scheme; and step 5, adjusting the train according to the optimized train operation scheme.
