The lighting of the train is one of the important passenger services that influence the image of the railways. Although the first-train operated on April 16, 1883 from CST from Mumbai to Thane, the train lighting system through the hub driven dynamo was pioneering by M / s. J. Stone & Co. arrived at Indian Railways only in 1930. The Dynamo / Brush-less alternator driven from the shaft via flat belts / 'V', supplies the load when the train is moving and charges the batteries. The batteries supply the load when the train is stationary. Train Lighting Systems: The following train lighting systems are currently in use Axle driven system that works with 110 V DC supply. Mid-generation with generation of 415 V, three-phase AC 110 V generation. Finalisation of generation with 3 phases 415 V and use of AC 110 V. Finalisation of generation with generation of 3 phases 750 V and use of AC V. It has been decided that all coaches being built will have only a 110 V system. Coaches operated in the 24 V system have already been converted to the 110 V system. Generation of axles working in DC. 110 V. Supply: This system has proved to be more reliable and capable of satisfying the future increase in load. Therefore, it has been adopted as a standard for all future self-generating constructions, coaches. In this system, 4.5 kW brush-less alternators are driven via V-belts from the shaft. 11O V, 120 Ah lead-acid batteries arranged from 3-cell Mono-block units are provided in the B.G. Coaches Four numbers of emergency power terminal boxes for B.G. And a number for M.G. They are provided at each end wall to interconnect the trainer to the adjacent trainer to receive power, in case the generation fails. A number emergency terminal box is provided centrally on each side of the base frame to facilitate the charging of the external source battery. For BG AC coaches, brush-less alternators of 18 KW / 25 KW are used. Two alternators of this type are used in AC-2T / AC-3T / Chair Cars and only one alternator is used in the first AC coach.
