The construction of diesel shunters began in 1920 in France, in 1925 in Denmark, in 1926 in the Netherlands, and in 1927 in Germany. After few years of testing, hundreds of units were produced within a decade. Diesel-powered or "oil-engined" railcars, generally diesel–mechanical, were developed by various European manufacturers in the 1930s, e.g. by William Beardmore and Company for the Canadian National Railways (the Beardmore Tornado engine was subsequently used in the R101 airship).

Diesel Locomotive Works plans to increase it to 275 based on the current demand.Since inception,DLW has produced total 8099 locomotives (up to 31st January, 2018) of various types. DLW now manufactures“More than one locomotive a day”. DLW manufactured 334 diesel-electric locomotives in last financial year 2016-17, which is the highest ever loco production by any loco manufacturing unit in India and bagged the “Best Production Unit Shield” for the second successive year. DLW locomotives have power outputs ranging from to . Currently DLW is producing EMD GT46MAC and EMD GT46PAC locomotives under license from Electro-Motive Diesels (formerly GM-EMD) for Indian Railways. Some of
