The Kalka-Shimla narrow-gauge track is a 96.6 kilometres long working rail link with a 0.762-metre gauge. The line was opened in November 1903, just about 12 years after the Delhi railway line was linked to Kalka in 1891.
The 120-year-old Kalka-Simla Railway will get an image makeover for the first time since it was put into service with swanky new indigenously manufactured coaches, each with a mini pantry and bio-toilets.
