- Importance
- The milestone accelerated India's transition away from steam locomotives and strengthened domestic production of modern diesel and electric traction.
The year 1961 represented an important turning point in the technological evolution of Indian locomotives.
Diesel Locomotive Works was established at Varanasi to build diesel locomotives, while Chittaranjan Locomotive Works began manufacturing electric locomotives.
Steam traction had powered India's railway network for more than a century, but diesel and electric locomotives offered greater efficiency and operational advantages.
Over the following decades, diesel locomotives became common across non-electrified routes while electric locomotives progressively took over electrified corridors.
The change fundamentally altered railway operations and eventually led to the near-total dominance of electric traction on India's broad-gauge network.
