Mountain Railways of India – Darjeeling Himalayan Railway (New Jalpaiguri → Darjeeling)

Overview

The Darjeeling Himalayan Railway (DHR), popularly known as the “Toy Train,” is one of the most iconic heritage railways in the world. Stretching from New Jalpaiguri in the plains of West Bengal to the cool hill town of Darjeeling in the Himalayas, it combines engineering marvels with breathtaking landscapes. It was the first of the three Indian mountain railways to be recognized by UNESCO as a World Heritage Site in 1999.

Quick facts

  • Route: New Jalpaiguri (NJP) — Darjeeling (DJ).
  • Length: ~88 km.
  • Gauge: 2 ft (narrow gauge).
  • Elevation: climbs from 100 m at NJP to 2,200 m at Darjeeling.
  • UNESCO status: Inscribed in 1999 as the first “Mountain Railway of India.”

Historical background

Built between 1879 and 1881 by the Darjeeling Himalayan Railway Company, the line was designed to link the tea plantations and hill station of Darjeeling with the plains. Ingenious engineering solutions — such as zigzags and loops — allowed the railway to climb steep gradients without a rack system. It became a lifeline for the region’s tea trade, local economy, and tourism.

Engineering brilliance

The DHR is famous for its loops and reverses:

  • Batasia Loop: the most photographed stretch, where the train curves around a spiral with panoramic views of Kanchenjunga.
  • Agony Point: a sharp double-reverse curve that is both scenic and technically daring.
    The line demonstrates how narrow-gauge mountain railways could conquer steep Himalayan terrain through innovative alignment rather than heavy engineering like rack systems.

Rolling stock & locomotives

The DHR is home to historic B-Class steam locomotives, built by Sharp, Stewart & Co. between 1889 and 1925. Many of these engines are still operational, hauling heritage trains for tourists. Diesel engines also operate for regular services, but the steam-hauled runs preserve the railway’s colonial charm.

The journey — what passengers see

The ride is an immersion into Himalayan landscapes and cultures:

  • Dense forests, tea plantations, and small hill villages.
  • Views of snow-clad peaks, especially Kanchenjunga.
  • Roadside bazaars where the train passes so close to shops and houses that passengers can interact with locals.
    The slow pace — about 6–7 hours end to end — allows travelers to soak in the atmosphere of the hills.

UNESCO significance

The DHR was inscribed for its pioneering role in mountain railway construction, its continued use of historic rolling stock, and its cultural importance in shaping the identity of Darjeeling. It remains an outstanding example of a hill railway harmoniously integrated into its landscape.

Challenges & conservation

Urban encroachment, landslides, and modernization pressures threaten the DHR’s heritage character. Yet, government and heritage bodies actively maintain steam locomotives, stations, and structures to preserve its authenticity.

Why the DHR matters

Beyond heritage, the Darjeeling Himalayan Railway is a cultural symbol — a lifeline for hill communities, a tourist magnet, and a nostalgic journey into the colonial-era hill station charm of Darjeeling.
