A Glimpse of Modern S&T Equipment’s over the Zone.

1. Panel Interlocking (PI):

Relay based Panel interlocking is a signalling system, which assures the best standard of safety and eliminates the accidents arising out of human errors and provided for smaller station yards.


2.Route Relay Interlocking (RRI)


Route Relay Interlocking is provided at major junctions and yards, where large numbers of train movements are required and available at four major junctions’ yards, viz. Vijayawada Jn., Kazipet Jn., Secunderabad Jn. and Dornakal Jn. in South Central Railway.


3.Electronic Interlocking (EI)



South Central Railway has adopted the high reliability state of art of interlocking technology in the form of computer controlled interlocking and the first system was commissioned at Kavali station on Vijayawada division on 10.07.1994.


4.Safety at Level Crossing Gates:

Level Crossing Gates in the station area and important gates in the block section are controlled by the signals. Such gates are called interlocked LC gates and enhance safety of the road users as well as trains. Telephone communication at level crossing gates is a safety tool to ensure the closure and opening of gates at appropriate time.

5.LED Based Signals:

High reliability LED Signals give advanced information of section ahead to the driver for appropriate control of the train.
