SIGNAL AND TELECOMMUNICATION DEPARTMENT FOR SPEED, SAFETY, RELIABILITY AND PUNCTUALITY
Migration of Technology from mechanical lever operated semaphore Signal & overhead communication to panel interlocking with LED signal & OFC based communication was really fast in Solapur division. At Solapur we always look forward to adopt state of the art advance technology for safe & reliable operation of train.
There have been considerable increase of Assets, still significant reduction in Signal failure could be achieved by adopting Remote Online Conditional Monitoring of Signalling equipment and continuous knowledge up gradation of maintainer (Mechanical to relay based color light Signalling, Overhead to OFC communication). Out motto is to reduce the maintenance efforts while maintaining the reliability
To keep pace with change in technology a Divisional training Center have also been set up with in-house recourses
Divisional Training Center Daund: To keep pace with rapidly changing technology, continuous knowledge up-gradation of the maintainer is essential hence special emphasis has been given on providing in-house training to maintainer. Week maintainers and key resource persons are being identified by depot in-charge continuously. Confidence Building Course is being conducted by the KRP on various Signalling & Telecom subject including hands on training. Our MOTO is to provide minimum 2% man-days training to each maintainer in a year.
