1. A method for mixed operation of a section of railroad line, the section of railroad line being trafficable by trains equipped with a train control system and by trains not equipped with the train control system and the section of railroad line being provided with at least one switch, which comprises the steps of:
indicating the section of railroad line as occupied in an event that a train not equipped with the train control system is to enter the section of railroad line from a direction of a side track, wherein an occupied indication is triggered by a first throwing of the switch in the direction of the side track;
cancelling the occupied indication after the train not equipped with the train control system has passed through, a cancelation being triggered by a second throwing of the switch in a direction of the section of railroad line; and
carrying out a track clearing run at a reduced speed of operation to ensure that the driver of the equipped train can make a visual inspection to allow timely braking in the event of obstacles on the section of line using a train equipped with the train control system, by either:
after the second throwing of the switch, carrying out the track clearing run on the section of railroad line using the train equipped with the train control system before the section of railroad line is released for operation by the trains equipped with the train control system;
or
prior to the second throwing of the switch, carrying out the track clearing run using the train equipped with the train control system from the direction of the side track before the section of railroad line is released for operation by the trains equipped with the train control system after the second throwing of the switch.
