The Demodara Loop is a colonial-era engineering masterpiece where the railway spirals around a hill and passes beneath the station. Inspired by a turban’s folds, this rare 441-foot loop overcomes steep gradients, offering travelers a unique journey through Tunnel 42 amidst breathtaking highland tea estates.

Hidden amidst the emerald tea plantations of Sri Lanka’s Uva Province is one of the country’s greatest feats of railway engineering: the Demodara Loop. Located in the small town of Demodara, just a short distance from the popular hill station of Ella, this iconic spiral railway track is not only a masterpiece of colonial-era infrastructure but also a symbol of ingenuity and adaptation to the island’s challenging terrain.

A Scenic Journey to the Highlands

During long weekends, particularly around holidays such as Poya Day, thousands of travelers flock to Sri Lanka’s central highlands. The journey along the newly developed road from Kandy through Randenigala to Badulla, and returning via Nuwara Eliya, is a popular route for those seeking cooler climes and lush scenery. Along this route, travelers can detour to Demodara, nestled within rolling tea estates and enveloped in misty hills.

What Is the Demodara Loop?

The Demodara Loop is a unique railway formation where the track literally loops around and passes under itself, allowing trains to ascend or descend steep terrain within safe gradient limits. This ingenious design enabled trains to travel from Colombo to Badulla without exceeding the maximum gradient of 1:44 set by the Ceylon Government Railway (CGR) during British colonial rule.

The most remarkable feature of the loop is that the Demodara Railway Station sits directly above a tunnel through which the railway line passes. Trains entering the station travel around a circular path and pass through Tunnel No. 42, emerging below the station from the same hillside. The entire loop spans approximately 441 feet, making it one of the rarest railway constructions of its kind in the world.

The Legend Behind the Loop

According to local folklore, when British engineers were struggling to overcome the steep elevation at Demodara, inspiration struck in the most unexpected way. Observing a local Kangany (a plantation supervisor) tie his turban—winding it in a loop around his head—gave them the idea to loop the railway line in a similar fashion. While there’s no historical record confirming this story, it continues to be a charming and widely shared tale among locals and tourists alike.

A Forgotten Treasure

Despite its historical and engineering significance, the Demodara Loop is largely under-promoted compared to the nearby Nine Arch Bridge. Walking along the track from the station through the tunnel offers a sense of awe—but also reveals signs of neglect. Water drips from the tunnel roof, loose railway sleepers are visible, and the interior remains dark even at midday. These factors underline the urgent need for conservation and better tourist infrastructure.

Nonetheless, the journey remains captivating. After exiting the tunnel, visitors can follow a steep footpath that leads up to Spring Valley Road, offering a panoramic view of the entire loop and the surrounding countryside.

Historical and Cultural Connections

Demodara also holds cultural significance. In the late 19th century, large numbers of Tamil workers from the Pudukkottai region in South India settled in Uva Province to work on tea plantations. Some believe the name “Demodara” itself may be derived from “Ten Madura”—a reference to an ancient Tamil city in southern India. Scholar S.L. Gunesegaram, in his 1985 book Selected Writings, suggests that “Ten Madhura” or “Southern Madura” referred to a coastal city that once thrived as a center of Tamil culture before being lost to the sea.

Evidence of this South Indian heritage can still be seen today. The Murugan Kovil in Haputale, for example, features granite pillars imported from India, inscribed with the names of donors from the Theavar clan of Pudukkottai—dating back to around 1900.

A Stamp of Recognition

In recognition of its engineering brilliance, the Demodara Loop was featured in a commemorative postage stamp series titled Civil Engineering Marvels of Sri Lanka Railways. Released as two Rs. 5 stamps, the series showcases both the Demodara Loop and the Nine Arch Bridge, another iconic structure of the hill country railway line.

The stamps, designed in a rare diamond shape, celebrate these enduring feats of colonial railway construction that continue to serve Sri Lanka’s transport system to this day.

Spiral Engineering on a Global Scale

The Demodara Loop stands proudly alongside other famous railway loops in the world, such as the Septemvri-Dobrinishte Loop in Bulgaria and the Tehachapi Loop in California, USA. However, what sets Demodara apart is its unique structural layout—being the only railway loop in the world where a station is built directly above a tunnel within the same loop.
