An Analysis Of The Work Of Passengers Trains On Twozone Sections And Their Alert Automation, N. S. Tokhirov Jul 2019

An Analysis Of The Work Of Passengers Trains On Twozone Sections And Their Alert Automation, N. S. Tokhirov

Central Asian Problems of Modern Science and Education

Company "Uzbekistan railways" has made a great contribution to the safety of passenger traffic. It is expected that passenger trains will have a number of factors affecting the large passenger traffic in the coming days and will be in the future. That is why passenger trains require that the issuance of warnings from workers of the running facilities, electricity, signaling and communications, as well as station attendants at the station by dispatchers, be accurate and error free. This article describes the automation of issuing warnings for trains and trains at two zones
