Ballari Jn - Look around and enjoy the station. A sacred place where Mahatma Gandhi once spent 8 hours. - Vishwanath Joshi

** IR has done partial/isolated automatic signalling system between 2 stations and breaking a section (of say 10kms) into 2 sections (of 5 km each) by installing additional signal with cabling. thereby decreasing the distance between 2 stations and increasing the sectional capacity. It is a nice step.
** Above means there may be 2 trains at a given moment between 2 far off consecutive stations.
** But why going for just partial automation, with cabling already done, it would be better to adopt the same system by installing signals at uniform distance...

say every 2 kms or 3 kms through out the route.
** Currently longer sections limit the sectional capacity. Having signals at uniform distance throughout the route will remove this limitation. Such systems had long been used in advanced railway systems in developed countries.
