Diesel Loco Works, Varanasi

When I visited Diesel Loco Works in Varanasi in February 2008, I was determined to focus on one aspect that is neglected by most rail fans; how does DLW manufacture the key ingredient in diesel-electric loco, the power plant.

I sincerely appreciate efforts by Shri S.M. Bhardwaj, General Manager, DLW as well as Shri Niraj Kumar, Chief Mechanical Engineer and Shri Anoop Kumar, Chief Design Engineer (Mechanical) to make my visit most remarkable that I'll remember it for life time.

Little known to the world outside India is, DLW Varanasi still manufactures locos based on ALCO 251 power plant that has been indigenously refined and now delivers more throughput than original 2,600 SHP.

The story begins with building engine block.
