The Idalgashinna Railway Tunnels, located in Sri Lanka's hill country, are a remarkable feat of engineering and a significant feature along the Main Line railway.

Situated in the Badulla District of Sri Lanka's Central Province, the Idalgashinna Railway Tunnels are positioned between the towns of Haputale and Ohiya. This area is renowned for its picturesque landscapes, including misty mountains and sprawling tea plantations.

The tunnels were constructed during the late 19th and early 20th centuries, during the British colonial period. They were essential for connecting the central highlands with the rest of the island, facilitating the transportation of tea and other goods from the hill country to coastal regions for export.

The Idalgashinna Railway Tunnels consist of three main tunnels. These tunnels were meticulously carved through the rocky terrain to allow the railway line to pass through the hills.

Building the tunnels required extensive engineering expertise, considering the challenging topography and geological conditions of the region. Engineers had to contend with solid rock formations and ensure the stability and safety of the tunnels for train traffic.

The area surrounding the tunnels is known for its breathtaking natural beauty. Passengers traveling by train through the tunnels are treated to stunning views of mist-covered mountains, lush green valleys, and cascading waterfalls, making the journey a memorable experience.

The train journey between Ohiya and Idalgashinna, which includes traversing the tunnels, has become a popular tourist attraction for both domestic and international visitors. Many travelers specifically seek out this experience to admire the natural beauty of the hill country and to enjoy the nostalgic charm of train travel.
