Replacement of existing mechanical gears at important stations alone will cost Rs 1,000 crore.

Another Rs 600 crore is required for installing last vehicle check device on the entire Delhi-Mumbai line. Work on the Mathura-Kota-Ratlam section is already complete.

The last vehicle checking device helps in knowing whether an entire train has reached a station. This is done by axle counting between two stations.The device will be particularly useful for goods trains in which wagons often part due to their large numbers.

At present, station masters have to manually check whether all the wagons which left the previous station have reached. This leads to delay and safetyhazard in case a wagon is left behind.

The Railways plans to take up track circuiting works on a priority.A new circuiting system called route relay interlocking (RRI) has recently been installed at the Delhi main station. It will be installed in over a dozen more stations in two years.

The present system has been designed by Seimens using K-50 relay groups and domino type control and indication panels.

The RRI installation at Delhi has cost Rs 15.75 crore. The new system can handle up to 1,122 route control movements, which is highest in the country, as compared to 530 earlier. This will help in additional reception and dispatch facilities to and from various platforms to yard remodelling.Expenditure to be incurred on installation of this device varies from each station on the basis of traffic being handled. While it is Rs 12.61 crore for Patna and Rs 11.82 crore for Simhachalam, it as low as Rs 2.5 crore for Sealdah.
