Nilgiri Mountain Railway
An engineering marvel when it was first opened more than a century ago, the Nilgiri Mountain Railway that links Mettupalayam to the renowned hill station of Ooty, remains a treasure in India’s extensive railway system. Recently accorded World Heritage Site status by UNESCO as part of India’s mountain railways, the Nilgiri Mountain Railway (NMR) line was first proposed in 1854 but only completed in 1908 due to a variety of technical difficulties given the mountainous terrain. The 46 km long meter-gauge single-track railway scales up the Nilgiri hills to an elevation of 2203 m (7228 ft) in Ooty.
The Nilgiri Mountain Railway is the steepest mountain railway in Asia, with an average gradient of 4.6 degrees. Typical railway gradients are usually less than a third of a degree while most mountain railways operate on gradients of only 1.5 degrees. The steep gradients make the use of the rack and pinion system crucial for safe operation. Despite the enormous challenges posed by the terrain, the Nilgiri Mountain Railway, essentially unchanged from the original system put in place at the end of the 19th century, has only suffered one accident in more than a hundred years of continuous operation.
The train itself is made up of charming blue and yellow wooden coaches with large windows, and is affectionately known as the Nilgiri Toy Train. Some of the last steam locomotives in active duty anywhere in the world are used for the strenuous uphill journey from Mettupalayam to Coonoor. The Swiss-made steam rack locomotives on the Nilgiri Mountain Railway are between 50 and 80 years old. From Coonoor to Ooty, where the gradient is gentler, a diesel locomotive is used.
The first part of the journey from Mettupalayam to Kallar is surrounded by rice fields stretching into the mountains. The next portion is the steep climb up the Nilgiri Hills into Coonoor, the small hill station known for its tea plantations. Coonoor is the only major stop in the Nilgiri Mountain Railway before Ooty. There are smaller way stations along the way, with their main purpose being to replenish the locomotives with much needed water. The rail goes uphill after Coonoor at a gentler slope before going downhill into Ooty at the end of the line. A breathtaking journey with no less than 208 curves, 250 bridges and 16 tunnels, the Nilgiri Mountain Railway is both a marvel of engineering and a magnificent treat for the eyes.
Nilgiri Mountain Railway
The Nilgiri Mountain Railway is the only rack railway in India, which facilitates the climb up the steep ramp into the hills. One of only about 30 or so such vintage cog railways in the world, the Nilgiri Mountain Railway has an extra rail running in the middle of the track that prevents the train from slipping or sliding back. This mechanism, also known as the Alternate Biting Teeth (Abt) system, is used on many mountain railways around the globe and has been utilized effectively in the Nilgiri Mountain Railway since its inception.

Changing the Nilgiri Landscape
The case for the Nilgiri Mountain Railway was first made by the British colonial masters of India in the mid 1800’s and after overcoming severe financial and technological obstacles, became a reality at the turn of the century. Before the railway, access to the Nilgiri hills was mainly through grueling journeys on horses or bullock carts. The Nilgiri Mountain Railway, by facilitating the movement of people and goods into the hills, helped change the socio-economic conditions of the region and turn it into one of the most popular tourist destinations in south India.

The Nilgiri Mountain Railway Journey
The train runs at a leisurely average speed of about 10.4 km per hour, taking almost five hours to complete the 46 km journey going uphill. The slow pace allows riders to take in the mesmerizing beauty of the Nilgiri hills along the route to Ooty. Majestic eucalyptus groves and panoramic views of tea plantations are interspersed with colonial-era way stations and quaint tribal villages. The eternal charm exuded by the lofty peaks of the Nilgiris make the train journey an enchanting experience.
