The article presents one of the functions of modern ATC systems – unattended (i.e., without a driver in the cab) reversing of a metro train at a terminal station. Selected elements of the solution are presented using the example of the implementation of this function in the SOP-2P system. Unattended reversing of metro trains allows for a reduction in the number of drivers operating a given line and shortens the time required for trains to reverse at the terminal station.In August 1998, the Prague Public Transport Company announced a public tender for the modernization of safety equipment for line A of the Prague Metro. The Czech company AŽD Praha, in agreement with the Polish side, submitted the LZA system for this tender, consisting of the SOP 2P system in the ATP (automatic train protection) part and the ACBM system in the ATO (automatic train operation) part. Both systems together form an ATC class system.
The SOP 2P system is a modernized, developed, and user-requirement-adapted version of the field-proven SOP-2 system used in the Warsaw Metro. The SOP 2P system was developed in cooperation with the Lodz University of Technology and Bombardier Transportation Zwus, and it is manufactured in Katowice.
The ATO part of the system was developed and manufactured by AŽD. The technical solutions of this system’s devices are based on the AVVČD system produced by AŽD and implemented on the Czech Railways.
After the system installed on line A of the Prague Metro was put into operation in 2006, work began on introducing the function of unattended (without a driver in the train cab) reversing of metro trains at the terminal station into the system.
