The UNESCO 'toy train': With 103 tunnels, 917 curves and 988 bridges spanning over 20 stations, the 96.6 kilometer (60 mile) Kalka-Shimla line is a spectacular feat of engineering.

Kalka-Shimla toy train: The line connects the sleepy railway station of Kalka with Shimla, a hill city that was once the summer residence of the British Raj government.

An engineering feat: The five-hour ride takes you from an altitude of 658 meters in Kalka to a height of 2,075 meters in Shimla, passing through fantastic hilly scenery that's dotted with viaducts, remote villages, deep forests and the Himalayas in the distant background.

The summer capital: To escape the unbearable hotness of the Delhi and Kolkata summers, India's British colonial rulers decided to make Shimla the summer capital.

Shimla: Highlights in this lovely small city include the Neo-Gothic Christ Church.

Bridge 541: Resembling the Scottish Glenfinnan Viaduct, famed for its appearance in the Harry Potter films, Bridge Number 541 -- with 34 arches and a height of 23 meters -- is India's highest railway bridge.

Himalayan views: Be it summer or winter, you're guaranteed fantastic views of the picturesque Himachal Pradesh region. The unhurried trip is perfect for capturing the panoramas and enjoying the scenery.

A century-old railway: In operation for more than 100 years , the railway has entered the 21st century generally intact and remains a definite draw for train aficionados.
