There are plenty of famous railway journeys in India. The Darjeeling Himalayan Railway, the Nilgiri Mountain Railway and the Kalka Shimla Railway attract railway enthusiasts from around the world, and quite rightly so. But tucked away in the foothills of the Himalayas is another railway that deserves far more attention.

The Kangra Valley Railway runs for around 164 kilometres from Pathankot in Punjab to Joginder Nagar in Himachal Pradesh, winding through the Kangra Valley beneath the snow-capped Dhauladhar mountains. Built in the 1920s, this 2 ft 6 in narrow-gauge railway is one of India's great surviving mountain railways, yet it remains remarkably little known outside India.
​
For railway enthusiasts, it offers something particularly appealing: a genuine working railway, spectacular scenery, fascinating engineering and far fewer tourists than the better-known Himalayan lines.
​
And for anyone who loves the idea of seeing India by rail, it is difficult to imagine a better place to start.

A railway built for more than sightseeing

The Kangra Valley Railway was not originally built as a tourist attraction. Its story is closely connected with one of the great engineering projects of the early 20th century: the development of hydroelectric power in the mountains. The proposed Shanan hydroelectric project near Joginder Nagar required enormous quantities of machinery and materials to be transported into the Himalayan foothills. Getting heavy equipment there by road would have been extremely difficult, so a railway was the obvious solution.

Construction began in the mid-1920s and the line opened to freight traffic in December 1928. Passenger services followed in April 1929.

The railway connected the main railway network at Pathankot with the towns and villages of the Kangra Valley, eventually reaching Joginder Nagar. Although its original purpose was industrial, the railway quickly became an important part of life in the valley.
​
The line was also built economically. Rather than attempting to conquer the mountains with enormous gradients and expensive tunnels, the engineers followed the contours of the landscape. The result is a railway that twists and turns through the foothills, climbing gradually while offering extraordinary views along the way.
Today, the line remains a remarkable piece of railway engineering.

164 kilometres of Himalayan scenery

The numbers tell only part of the story. The Kangra Valley Railway has around 1,000 bridges and culverts, 484 curves and just two tunnels. Its highest point is at Ahju, at approximately 1,290 metres above sea level. The railway's relatively modest gradients were achieved by allowing the track to follow the natural shape of the valley. Rather than simply heading upwards, it meanders through fields, villages, forests and tea plantations, repeatedly changing direction as the landscape opens out.

And then there are the mountains. The great Dhauladhar range forms a spectacular backdrop for much of the journey. On a clear day, the contrast between the little narrow-gauge train, the green Kangra Valley and the enormous Himalayan peaks is extraordinary.
​
This is one of the reasons the Kangra Valley Railway can feel so different from the more famous Himalayan railways. On the Kalka Shimla line, the railway spends much of its journey climbing through densely forested hills. The Kangra Valley Railway has a much more open character. You can look across broad stretches of countryside towards the mountains rather than simply seeing the landscape immediately beside the track.

From Palampur to Baijnath

One of the most scenic sections lies around Palampur, where the railway passes through the famous tea-growing country of the Kangra Valley. Palampur is surrounded by tea gardens, with the Dhauladhar mountains rising dramatically behind them. The railway threads its way through this landscape before continuing towards Baijnath Paprola and eventually Joginder Nagar.

The journey also passes close to the historic town of Baijnath, home to the remarkable 13th-century Baijnath Temple, dedicated to Shiva.

Beyond Baijnath, the railway tackles some of its more demanding gradients as it climbs towards Ahju. The line reaches its highest elevation here before descending towards Joginder Nagar.

There is something wonderfully old-fashioned about travelling this way. Stations are often small and unassuming, trains move at a leisurely pace, and the railway remains closely connected to the communities through which it passes. This is not a railway where the journey is simply a means of getting somewhere else. The railway itself is the experience.

Bridges, curves and mountain engineering

For railway enthusiasts, the Kangra Valley Railway is fascinating even before you look out of the window.

The line's approximately 1,000 bridges and culverts reflect the challenge of constructing a railway through a mountainous landscape. Some are substantial structures crossing rivers and deep valleys, while others are small enough to pass almost unnoticed as the train continues on its winding route.

The line also contains two tunnels, but compared with other Himalayan railways, tunnels are surprisingly scarce. This is largely because the engineers designed the route to follow the natural contours of the land.

There are almost 500 curves, too, giving the railway its characteristic meandering journey through the valley. It is a reminder that narrow-gauge railways were often ingenious solutions to difficult terrain. The smaller gauge allowed engineers to build a railway through landscapes where a conventional main line would have been considerably more difficult and expensive.
​
The Kangra Valley Railway may lack the international fame of the Kalka Shimla Railway, but from an engineering perspective it is every bit as intriguing.

A railway that has survived against the odds

The survival of the Kangra Valley Railway is remarkable.
 
Like many Indian branch and mountain railways, it has faced periods of disruption and uncertainty. During the Second World War, part of the track was dismantled to provide steel for the war effort. It was eventually restored and returned to service.

The railway was also affected by the construction of the Pong Dam in the 1970s, when around 25 kilometres of the line had to be realigned.

More recently, severe flooding in Himachal Pradesh in 2022 caused extensive damage to sections of the railway. Services were disrupted for several years while repairs and restoration work took place. The line has subsequently returned to operation, once again giving passengers the opportunity to experience one of India's great mountain railways.

Its survival is important for another reason. The Kangra Valley Railway is on India's UNESCO World Heritage tentative list as part of the proposed extension of the Mountain Railways of India. UNESCO describes the railway as an important surviving example of a mountain railway and notes its cultural and engineering significance.
​
The three better-known mountain railways, Darjeeling, Nilgiri and Kalka Shimla, already form the UNESCO-listed Mountain Railways of India. The Kangra Valley Railway offers another fascinating chapter in that story.

Why is the Kangra Valley Railway so little known?

This is perhaps the biggest mystery.

India has several railway journeys that have become international tourist attractions, yet the Kangra Valley Railway remains comparatively obscure. Part of the reason is simply geography. The railway is away from India's major tourist circuits, and visitors heading into the Himalayas often have their sights set on Shimla, Manali or Dharamsala. It also lacks the instantly recognisable reputation of the Darjeeling Toy Train. There is no famous loop comparable with Batasia Loop, and no hill station at the end of the line that attracts quite the same volume of visitors as Shimla or Darjeeling.

But for railway travellers, that can be an advantage. The Kangra Valley Railway still feels like a railway that belongs to the valley rather than a railway designed primarily for tourists. You can watch everyday life unfold at the stations, see local passengers going about their journeys and travel through landscapes that have not been transformed into a succession of tourist attractions.
​
For anyone interested in India's railways, that authenticity is part of its appeal.

The Kangra Valley Railway by narrow gauge

The railway is built to 2 ft 6 in (762 mm) narrow gauge, the same gauge used by the famous Kalka Shimla Railway. India's railway network historically used several different gauges, reflecting the enormous scale of the country and the different requirements of main lines, branch routes and mountain railways.

Narrow gauge was particularly useful in mountainous areas because it allowed tighter curves and generally required less substantial infrastructure than broad-gauge lines. That makes the Kangra Valley Railway particularly interesting when considered alongside India's other surviving gauges.

And that is exactly what makes Darjeeling Tours' Rail on All Gauges tour so unusual.

Experience the Kangra Valley Railway with Darjeeling Tours

The Rail on All Gauges tour is designed around one of the great pleasures of travelling through India by train: experiencing the remarkable variety of its railway network.

Running from November to December, the tour combines railway journeys with cultural sightseeing and explores all three of the principal gauges still found on India's railways: narrow gauge, metre gauge and broad gauge.

The Kangra Valley Railway is one of the highlights.

The itinerary allows three days in the Kangra region, combining journeys on the railway with visits to some of the area's fascinating sights. From Joginder Nagar and Baijnath Paprola to Palampur and beyond, there is time to experience the railway as part of the landscape rather than simply ticking off a short tourist train ride.

The tour also includes a visit to the Shanan hydroelectric power station, the very project that helped bring the Kangra Valley Railway into existence. The Shanan scheme has its own remarkable railway engineering, including the steep cable-worked incline used to transport materials towards the reservoir high in the mountains.

It is a particularly satisfying part of the itinerary because it connects the railway journey with the reason the railway was built in the first place.

More than a train journey

The Kangra Valley Railway is sometimes described as a "toy train", but that phrase can be slightly misleading.
There is certainly something charming about a small train winding through the Himalayan foothills, but this was a serious piece of infrastructure built to solve a very real engineering problem. It carried machinery for a major hydroelectric project, connected remote communities and became an important transport link for the Kangra Valley.

Today, its importance is rather different. It is a living piece of railway history, carrying passengers through one of the most beautiful corners of northern India. The railway connects the past and present in a way that few museum pieces can. And perhaps that is why it deserves to be better known.

If you have already travelled on the Darjeeling Himalayan Railway or the Kalka Shimla Railway, the Kangra Valley Railway offers the opportunity to discover another side of India's extraordinary mountain railway heritage. If you have never experienced an Indian narrow-gauge railway before, there can hardly be a more spectacular introduction.

With the Dhauladhar mountains on the horizon, tea gardens around Palampur, historic towns and temples along the route, and a railway that has survived almost a century of change, the Kangra Valley Railway is one of India's great hidden rail journeys.

For railway enthusiasts, it is a fascinating piece of engineering. For travellers, it is an unforgettable way to see the Himalayas. And for anyone who believes the best journeys are the ones that take you somewhere few other tourists have thought to go, it may just be India's most scenic hidden railway.
