PURPOSE: To surely recover the delayed time of a train by sufficiently acceding to the service demand of a passenger for labor and safety, without relying on the technique of an operator.

CONSTITUTION: Immediately before or after the start of a train, the predetermine start time which is predetermined in the operation plane of the train and the actual start time of the train which are memorized in an operation diagram memory means 51 are taken into a delayed or accelerated start time calculating means 53, and the delayed or accelerated start time as the time difference between both is calculated, and sent into a power running time calculating means 54. In the power running time calculating means 54, the recovery from the delay of the train is carried out by obtaining the initial power running time after the start from a start station on the basis of the delayed or accelerated time, and carrying out the power running operation of the train on the basis of the power running time.
