Darjeeling Himalayan Railway, West Bengal
Affectionately known as the 'Toy Train', this UNESCO World Heritage Site has been capturing hearts since 1881. The narrow-gauge railway chugs and whistles its way from New Jalpaiguri up to Darjeeling, climbing over 2,100 metres. The journey is an engineering
marvel, featuring dramatic loops and zig-zags to navigate the steep Himalayan terrain. You'll pass through bustling market towns where shops are inches from the track, verdant tea gardens clinging to the hillsides, and dense forests. The grand finale is the approach to Ghum, India’s highest railway station, followed by the descent into Darjeeling with potential glimpses of the mighty Kanchenjunga peak.
Kalka-Shimla Railway, Himachal Pradesh
Another UNESCO-recognised gem, the Kalka-Shimla line was built to connect the summer capital of British India. The journey covers 96 kilometres, navigating over 800 bridges and through 102 tunnels in about five to six hours. The train winds through pine forests and picturesque valleys of the Shivalik Hills, offering a slow-motion showcase of colonial engineering and Himalayan beauty. A key highlight is the stop at Barog station, with its charming architecture and proximity to the line's longest tunnel. This route isn't just about reaching a destination; it's about soaking in the tranquil, pine-scented mountain air from the comfort of a vintage carriage.
Nilgiri Mountain Railway, Tamil Nadu
The journey to Ooty is made unforgettable by this unique 'Toy Train', also part of the UNESCO Mountain Railways of India. What makes it truly special is that it's the only rack railway in the country, using a unique toothed track system to conquer Asia's steepest gradients. The train climbs from Mettupalayam, ascending from 326 metres to 2,203 metres. The route from Mettupalayam to Coonoor is especially breathtaking, passing over 250 bridges and through 16 tunnels as it winds through lush forests and rolling tea estates of the Nilgiri Hills. It’s a five-hour journey back in time, offering postcard-perfect views at every curve.
Konkan Railway (Mumbai - Goa)
Celebrated as one of modern India’s greatest engineering feats, the Konkan Railway is a stunning coastal journey. Connecting Maharashtra, Goa, and Karnataka, the route runs parallel to the Arabian Sea, sandwiched between the water and the majestic Western Ghats. Unlike the colonial hill railways, this line was built in the 1990s, carved through incredibly challenging terrain. The journey from Mumbai to Goa is a visual feast of lush green valleys, hundreds of river bridges, and over 90 tunnels. Particularly during the monsoon, the landscape is transformed into a vibrant green paradise, with waterfalls cascading near the tracks, making it one of the most scenic daytime journeys in the country.
The Pamban Bridge Journey (Mandapam - Rameswaram)
This is less of a mountain journey and more of a thrilling ride over the sea. The train from Mandapam to Rameswaram Island in Tamil Nadu crosses the historic Pamban Bridge, India’s first sea bridge, which opened in 1914. For about 15 minutes, the train travels slowly over the 2-kilometre-long bridge, with nothing but the turquoise waters of the Palk Strait on either side. It feels as though you are gliding on water. The experience of seeing the road bridge running parallel and fishing boats below makes this short but spectacular journey a must-do for any travel enthusiast exploring South India.
Kangra Valley Railway, Himachal Pradesh
Often overshadowed by its Shimla counterpart, the Kangra Valley Railway offers a different, but equally enchanting, Himalayan experience. Covering 164 kilometres from Pathankot to Joginder Nagar, this journey is celebrated for its uninterrupted, panoramic views of the magnificent Dhauladhar mountain range. The train meanders through lush valleys, past tea gardens in Palampur, and over nearly 1,000 bridges. It’s a slow, unhurried ride that provides an authentic glimpse into rural life in the Himalayan foothills. With very few tunnels, the snow-capped peaks remain a constant, breathtaking companion for much of the journey.
