Another purpose was to identify beautiful stretches en route which could be developed as tourist attractions. The team headed by Ajit Butail (57 years) vice- president, SOS, comprised Tribhuban Kumar (73 years), a retired station master who has spent most of his service span on the Shimla-Kalka rail-line; Sudesh Lall (61 years), former president of the Rotary Club (Shimla City); 65-year-old Vijay Sood, a businessman;Thakur Bharata; and Kunal Condillac (24 years), a student of biotechnology. The Heritage Walk took three nights and four days.

As the serpentine rail line goes through the picturesque countryside of the lower Himalayas, it goes through a succession of reverse curves of over 36 metre radii. The loops provide excellent walks and picnic spots over the hills and on top of the tunnels.

The Shimla-Kalka 30-inch gauge rail line was investigated and constructed in 30 years by a private company under the supervision of Chief Engineer H.S. Harington and agent of the Kalka-Shimla Railway. This railway was purchased by the state in 1906 and had cost Rs 1,71,77048 at the time of its construction.

Of the folklores woven around this rail-track two stand out the most. This line is supposed to have been built exactly on the track revealed by Bhalku, a common labourer who would march with a long shaft over the hills and claim that the track had been revealed to him by his devta. It is said that even the engineers were in awe of Bhalku’s supernatural powers and always consulted him.

Another folklore revolves around Colonel Barog who was engaged in the construction of the Barog Tunnel. He committed suicide when the two ends of the tunnel failed to meet. His grave is supposed to be located at the entrance of the incomplete tunnel.Raja Bhasin, who joined the Heritage Walk for a short distance at Barog found that though the incomplete tunnel is still there and is being used as a water reservoir for the SSB unit located at Dharampur, the grave is untraceable.

The SOS Heritage Walk team was greatly upset with the plastic litter found on the track and outside the small railway stations causing environmental hazard to the surroundings. It has been suggested to the authorities that the rail line maintenance gangs should be given special incentives and made responsible for keeping the track free of the plastic rubbish.

The deterioration in the environment was particularly noticeable along the Taksaal-Parwanoo-Kalka railway line . The track was so filthy that walking on it was a test of human endurance. It was ironical that on other side of the track lay a sign board ISO-9002, a rare honour for healthy industrial environment whereas the adjoining rail track was filthy. It has been suggested by the team that industrial houses along the track and in the vicinity should be made responsible for keeping the rail-track clean and green.
