The Barog Tunnel {also known as Tunnel No. 33} is the longest tunnel in the Kalka-Shimla railway, and houses a dark secret. The construction of the tunnel has a tragic tale. Under the leadership of Colonel Barog, the workers were instructed to bore from both {opposite} sides of the mountain, a fairly common procedure as it speeds up construction. But, due to a miscalculation, the colonel quickly realised both tunnels would not meet. He was fined by the government {a grand sum of INR 1} and had all his crew hate on him.
Because of the backlash, he shot himself and was buried in front of the incomplete tunnel. All these years later, it seems as though he never really died, or left the tunnel. At least his spirit didn’t.
