FIELD: transport.
SUBSTANCE: invention relates to electric rolling stick and aims at perfecting high-voltage chamber interlocking system. Proposed interlocking system comprises air reservoir communicated with feed main lines. Communication with air-operated interlocking devices, current collector gate that serves to lift current collector, is made via safety valve with the help of the first feed main line. Second feed main line is used to make said communication with air-operated valve that is connected via rod with aforesaid current collector. Said air-operated valve communicates via second feed main line with additional air-operated interlocking devices.
EFFECT: ruling out opening of said high-voltage chambers with lifted current collector and dead electric rolling stock.
