To replace railway interlocking device, it is necessary to set up a large number of signal cables and confirm wiring connections. There are possibilities of wiring errors that may cause serious transport disorders. We have developed a railway signal control system by optical LAN for the purpose of reduction of signal cables and wiring works.Moreover, all signal devices operate independently, designers have to handle all devices one by one and pay great attention to avoid causing harmful influence each other. We suggest data-driven control logic to make it easy to replace interlocking device. This logic is rearranged according to the field device in order to simplify and decrease design duties of designers.In this paper, we introduce this system, and describe software configuration of the system.

When replace railway interlocking devices, setting up of large number of signal cables and confirming of wiring connections are required. So, it is worried that serious transport disorder caused by human error in wiring works would occur. We have developed a railway signal control system utilized optical LAN to reduce the signal cables and wiring works. Moreover, all signal devices operate independently, designers have to handle all devices one by one and pay great attention to avoid causing harmful influence each other. We propose the data-driven method to make easy to replace interlocking device. This logic is rearranged according to the field device in order to simplify and decrease design duties of designers. In this paper, we introduce this system, and describe network transmission, safety-related communication and software configuration of the system.

“…The hooter will be louder as the level crossing nears, and finally it will be silent after the train passes by. There are several other methods proposed for automatically controlled railway gate at the level crossing, railway track switching mechanism and the movement of the train using sensors, micro controllers for reduction of railway accidents but all demand heavy investment [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Safety on the Indian Railways network is the end product of the cohesive fusion of its myriad parts . Railroad related accidents are more serious or deadly than other transportation accidents in terms of severity and death rate etc. The problem of railway accidents is not of safety standards but the execution of standards. Unmanned Level Crossings continue to be a matter of concern for Indian Railways as most of the train mishaps take place in these unmanned level crossings, . There are about 10,000 unmanned railway crossings in the country which account for around 40 per cent of accidents involving the railways. Therefore, Safety at unmanned level crossings is a cause of serious concern for railways and the public transporter is exploring various ways to address the issue. This paper presents a novel concept of an application to improve safety at unmanned level crossings without the burden of a huge infrastructure cost to the railways governing body. A low cost innovative reliable model has been proposed for automatic blockading of unmanned railway level crossings. . It explores too the quest for improved performance, and the need to focus not just on safety, but to contribute to the delivery of a cost-effective, efficient railway as well.
