In the paper target braking of underground trains as a function of an Automatic Train Operation (ATO) system has been described. Target braking relies on automatic train stopping at the stations, wherein braking process is fully controlled by a computer device and it is executed by a proper control of electric motors. Also functionality of the SOP-2 system used in the Warsaw underground is presented. The rolling stock powered by an AC and DC motor as an example of target braking has been taken into consideration. Finally, a direct braking simulation model created in the SIMULINK software has been discussed. The calculations of target braking performed for a Alstom Metropolis train are presented.

The paper describes AC and DC drives used in underground trains and braking methods of underground trains cooperating with an Automatic Train Operation (ATO) system. A train drive with an AC motor and a drive with DC motor with impulse and resistance riot has been described. An ATO system ensures automatic train piloting such as acceleration and braking. A type of this system, used especially on underground lines implements a direct position breaking. The precision of train braking depends on the motor control, which is particularly important during electrodynamic braking. The type of used drive affects on preciseness and quality of duty braking process. The concept of an efficient regulation of the duty braking, the control- execution system and a breaking quality indicator has been described.
