INTRODUCTION

It is a production unit owned by Indian Railways, for which it

manufactures diesel-electric locomotive and its spare parts.

To meet the increased transportation needs of the Indian

railways it was established in collaboration with M\s

ALCO(American Locomotive Company),USA.

Founded in 1961, the D.L.W. rolled out its first locomotive

three year later, on January 3, 1964. It manufactures

locomotives which are variants based on the original ALCO

design dating to 1960s and the and the GM EMD design of the1990s.

DIESELS ADVANTAGES OVER STEAM

They can safely be operated by one person, making them

ideal for switching/shunting duties in yards.

The operating environment is much more attractive, being

much quieter, fully waterproof and without the dirt and heat

that is an an inevitable part of operating a steam locomotive.

The thermal efficiency of steam was considerably less than

that of Diesel Engines.

feedback to the operator about the current position

and distance to be travelled etc.

CNC machines have the ability to edit or alter the

existing program in no time.
