The invention discloses a train control method based on the working condition. Working condition-control execution logic is preset in a train-mounted signal system and a train system in a train, and signal system actions or train system actions corresponding to the working condition are defined in the control execution logic. The train control method includes the following steps that an ATS determines the train needing to be controlled according to a train timetable or a manual command; the ATS sends a working condition command to the train-mounted signal system of the train; the train-mounted signal system executes the corresponding signal system actions according to the preset control execution logic, wherein the signal system actions comprise the action of sending the working condition command to the train system and the action of executing the corresponding train system actions through the train system according to the preset control execution logic; and the train system feeds the working condition command receiving condition back to the train-mounted signal system, and the train-mounted signal system feeds synthetic working condition execution feedback information back to the ATS. By the adoption of the train control method, remote control conducted through the ATS over train equipment under the unmanned condition is achieved.
