You are authorized to pass the Intervening Automatic Signal Nos.----- at ‘ON’/Semi Automatic Signal, Manually Operated Signal Nos.----- on being hand signaled by a railway employee and the Gate Stop Signals in ‘ON’ position cautiously up to the level crossing. Its the controller for a 2 aspect Signal. Automatic Train Operation: The ATO system drives the train automatically to achieve prescribed operational performance within the safety constraints imposed by ATP. As with the notorious situation of having different gauges, there are differing signal systems. It ensures that can drive several trains in fixed spatial distance from each other on a main track; in the range of stations the station block is applied. Semi-Automatic Stop Signal shall work as normal Automatic Stop Signal. The project ran between 2011 and 2014. Semi Automatic stop signal is identified by _____ a. This type of electronic block system requires fewer staff because the driver basically controls the block.
