Automated control of rail-road level crossing gates using axle counters and microprocessors

Many accidents take at rail-road level crossing (LC) gates which are either manually controlled or unmanned on Indian Railways. The cost of manning the gates involves huge recurring expenditure besides installation cost. The paper describes the present scenario of LC gates used on Indian Railways. The uses of track circuits and axle counters with their working principles are briefly discussed. A system for automated control of rail-road LC gates using axle counters (AC) and microprocessors has been developed using an 8085 microprocessor. The use of such a system is likely to reduce the number of accidents as well as recurring maintenance expenditure; and is aimed at facilitating safe as well as faster movement of trains. Indian Railways standards for broad gauge track have been referred to wherever required. (a)
