New Delhi: Travelling by train can be the most relaxing, and you could well undertake the most scenic journeys. But with steep climbs on almost-vertical hills, zig-zagging tracks on cliff faces, or narrow bridges over cyclone-prone, high-wind locations, some train rides can get your heart pounding a little bit faster and harder. Steep climbs, creaky trestles, and cliff-hugging curves are part of the ride on these rail routes.Here, we explore the most memorable railways routes in the world: 1.
