There are some UNESCO World Heritage Sites on Indian Railways. Can you count it?
B
Correct answer
Explanation
Indian Railways has two UNESCO World Heritage Sites: the Darjeeling Himalayan Railway (inscribed in 1999) and the Nilgiri Mountain Railway (inscribed in 2005). These narrow-gauge railways are recognized for their engineering excellence, historical significance, and the way they blend with the mountainous landscapes. A third site, the Kalka-Shimla Railway, was added later, making the answer to this question context-dependent on when it was written.
