Bharat Wagon & Engineering Co. Limited (BWEL) an ISO - 9001:2000 certified company is a central PSU. It was under the Ministry of Heavy Industries & Public Enterprises, Department of Heavy Industry till 13th August, 2008. From 13th Augustí08 (AN) the administrative control of this company has been transferred to Ministry of Railways.
BWEL was incorporated in December 1978 by take-over of two sick private wagon making companies, namely M/s Arthur Butler & Co. Ltd., Muzaffarpur and M/s Britannia Engineering Co. Ltd., (Wagon Division), Mokama. The third manufacturing unit was added to the company in the year 1983-84 at the Industrial Estate at Bela, Muzaffarpur for manufacture of LPG cylinders. In the year 1986, the company became a subsidiary of Bharat Bhari Udyog Nigam Ltd., Kolkata, under the Department of Heavy Industry.
Both, Muzaffarpur and Mokama Units are traditionally Wagon manufacturing factories. The layout, plant and machinery and locations are ideally suited for this product. With a rich experience of steel fabrication of over half century, BWEL possesses almost all the desired infrastructure facilities for heavy steel fabrication. Availability of 316 MT Brake Press at Mokama Unit, a rare asset, speaks in this direction. All the three manufacturing works are self-sufficient in power by way of installation of Captive DG sets. Operational ease is made possible due to location of the Works adjacent to important Railway Stations.
