of British Col. Barog************************
Col Barog was the person who was initially assigned the task of constructing this tunnel. He was a man of great morals. After the work of digging the tunnel reached mid-way, he found out that there had been a gross error on his part and the two ends of the tunnels fail to meet at the center. He took the blame upon himself and was very ashamed of his lapse. He was fined Re 1 for his error, but he could not bear the agony and committed suicide.
Stories say, that it is his ghost who keeps roaming in the tunnel area on his horse. What is more surprising is that he responds to the people who try to talk to him! He even engages in long discussions too. People who travel by train have never seen him, it is only the people who cross the tunnel on foot see him.
********************Story of the Black Witch***********************
Another story that entails a ghostly appearance is of a beautiful lady wearing a black sari. Her black eyes produce hypnotic effects on the onlookers. She is carrying a child in her lap but the child is malnoutrited and doesn’t seem to belong to her. The stories say that several years ago, dead body of a pregnant girl was found at this place and it is the same girl who is still roaming there with her child.
Barog WitchSometimes she stays silent and keeps looking while at other times she screams and disappears into the walls of the tunnel. Locals never claimed to have seen her but she is visible only to passing motorists and drivers. The reason for this is believed to be that some motorist or driver might have killed her in an accident.
The stories are no doubt captivating and so are the encounters that happen. Everyone has its own encounter to share about these ghosts of Shimla while there is no way to find out the truth.
