Diesel Locomotive Works (DLW) is a production unit under the ministry of railways. This was setup in collaboration with American Locomotive Company (ALCO), USA in 1961 and the first locomotive was rolled out in 1964. This unit produces diesel electronic locomotives and DG sets for
Indian railways and other customers in India and Abroad. Subsequently a contract for transfer of technology of 4000 HP Microprocessor Controlled AC/AC Freight (GT 46 MAC) / passenger (GT 46 PAC) locomotives and family of 710 engines has been signed with electro
motive division of GENERL MOTORS of USA for manufacture in DLW.
The production of these locomotives has now started and thus DLW is the only manufacturers of Diesel Electric Locomotives with both ALCO and General Motors technologies in the world

Machine shop work is generally understood to include all cold-metal work by which an operator, using either power driven equipment or hand tools, removes a portion of the metal and shapes it to some specified form or size. It does not include sheet metal work and coppersmithing. The function of all machine tools is to produce metal parts by changing the shape, size, or finish of a piece of material. The shape of a part made with a machine tool is limited by the types of motion the tool can apply.

Standard machine tools are grouped in six basic classes:
