All are expected to keep principles of Uniformity, Reliability, Availability, Maintainability & safety in mind at all iimes. Let us keep Railways Motto of Safety, Security & Punctuality always foremost in mind. I compliment the Members of signal Revision committee and all PCSTES for their sincere efforts and hard work in carrying out the meticulous revision of Signal Engineering Manual, 2020 edition.
