The Nilgiri Mountain Railway (NMR) is one of India’s most iconic and scenic railways. Built during the British colonial era, this heritage train is a testament to engineering excellence and natural beauty. Running through the Nilgiri Hills, it offers a breathtaking journey filled with lush greenery, misty landscapes, and thrilling curves.

This UNESCO World Heritage railway has a fascinating history and unique features that make it a must-visit attraction for railway enthusiasts and travelers alike. Here are five intriguing facts about the Nilgiri Mountain Railway that showcase its historical and cultural significance.

1. A UNESCO World Heritage Site

The Nilgiri Mountain Railway is one of the three heritage mountain railways in India, alongside the Darjeeling Himalayan Railway and the Kalka-Shimla Railway. It was awarded UNESCO World Heritage status in 2005 as part of the Mountain Railways of India.

This recognition highlights its historical importance, engineering brilliance, and cultural heritage. The Nilgiri toy train continues to attract thousands of tourists who seek a nostalgic journey through the Nilgiri Hills.

2. The Steepest Railway in Asia

One of the most remarkable engineering feats of the Nilgiri Mountain Railway is its steep gradient. With an inclination of 8.33%, it is the steepest railway in Asia. To tackle this challenging terrain, the railway uses a unique rack-and-pinion system, which helps the train climb steep slopes safely.

Unlike conventional railways, where the train wheels rely on friction, the rack-and-pinion system features a third rail with gears that engage with the train’s wheels, ensuring a smooth ascent and descent. This ingenious engineering allows the train to navigate the rocky Nilgiri terrain with ease.

3. A Century-Old Legacy

The Nilgiri Mountain Railway history dates back to the 19th century, when the British sought to create a railway line connecting the plains of Tamil Nadu to the hill station of Ooty. The project was initiated in 1854, but due to technical challenges, it was completed only in 1908.

The railway was originally built by the Madras Railway Company and later taken over by the Indian Railways. Despite being over a century old, the Nilgiri Mountain Railway continues to operate vintage steam and diesel locomotives, preserving its old-world charm.

4. The Scenic Route and Stunning Tunnels

The Nilgiri Mountain Railway route covers 46 kilometers (28.5 miles) from Mettupalayam to Ooty, passing through Coonoor and Lovedale. The journey takes approximately 5 hours, offering spectacular views of the Nilgiri Hills, dense forests, waterfalls, and tea plantations.

One of the most exciting aspects of the journey is passing through 16 tunnels, 250 bridges, and 208 curves. The most famous among them is the Kateri Bridge, the highest bridge on this route. The train’s slow speed allows travelers to fully appreciate the stunning landscape of the Nilgiri Hills railway.

5. A Star of Indian Cinema

The Nilgiri toy train has been featured in numerous Bollywood movies, making it a cinematic icon. One of the most famous songs filmed on this train is "Chaiyya Chaiyya" from the movie Dil Se (1998), featuring Shah Rukh Khan and Malaika Arora dancing on the train’s rooftop.

Apart from Bollywood, the train has appeared in regional films, documentaries, and television shows, further enhancing its popularity among travelers. The Ooty train journey remains a dream for many cinema lovers who wish to relive iconic movie moments.
