The Shivalik Express, affectionately referred to as the 'Toy Train' travels between the Indian town of Kalka and Shimla, capital city of the Indian state of Himachal Pradesh. The Toy Train's ninety-six kilometre narrow-gauge track through the Shivalik foothills of the Himalayas is one of three Indian mountain railways which together constitute a UNESCO World Heritage Site.
Built by British colonists, the Kalka-Shimla Railway is an extraordinary feat of railway engineering. The line negotiates 102 tunnels, more than 864 bridges and around 919 curves. Passengers have plenty of time in which to admire and marvel these features as well as the spectacular mountain panorama that line the route as the train makes its ascent to Shimla demands a leisurely pace.
