INTRODUCTION INDIAN RAILWAYS "Lifeline of the NationOwned and operated by the Government of India through theMinistry of Railways.Indian Railways is the world'sninth largest commercial or utility employerIndia's first train run between BombayandThane.

RAILWAY COUPLINGA coupling (or a coupler) is a mechanism for connecting rolling stock in a train. The design of the coupler is standard, and is almost as important as the track gauge, since flexibility and convenience are maximised if all rolling stock can be coupled together.

TYPES OF COUPLINGBUFFERS AND CHAINLINK AND PINCENTER BUFFER COUPLER etc.BUFFERS AND CHAIN

The vehicles are coupled by hand using a hook and links with aturnbucklethat draws the vehicles together.Vehicles havebuffers, one at each corner on the ends, which are pulled together and compressed by the coupling device.This arrangement limits the slack in trains and lessens shocks.Buffer And Chain Coupler

LINK AND PIN

Principle - The system suffered from a lack of standardisation regarding size and height of the links, and the size and height of the pockets.

CENTER BUFFER COUPLER(CBC)CBC overcome some of the limitations of the screw couplers -- limited draft load and energy absorption capacity, lack of anti-climbing feature, etc. CBC would also reduce the inter-coach distance.All new freight stock and container rake wagons, have CBC.A locking pin indicates whether the CBC portion is properly coupled or not.CENTER BUFFER COUPLER
