SOP 2P is an automatic train protection system, ATP, designed to assist the driver in driving the train in the safest way. It provides relevant signal information in the cab, continuous monitoring of the actions of the driver and the motion of the train. SOP 2P is designed to be transparent to the driver, as long as the traffic regulations are followed. If the traffic situation is regarded dangerous, SOP 2P will intervene and brake the train down to a safe speed, or stop the vehicle before an obstacle. Information on traffic situation obtained from interlocking equipment (track section), supplemented by additional information (section number, loop modification etc.) are formed into 47 bit telegram. The information signal after modulation and amplification supplies the transmission loops placed at the track. Antennas placed on the train, receive the telegram from the transmission loops and transmit it to the receiver, where a demodulation and reproduction of information contained in the telegram is performed. Information about speed are continuously compared with actual speed indicated by speed indicator. When the actual speed exceeds the speed limit the vehicle drive is automatically switched off and service braking is applied if necessary. If the speed is still not going to be lower an emergency braking is applied.
