The MEIL has taken enormous safety measures for the workforce in the execution of tunnel project in both packages.
In 7B, the MEIL is executing tunnel works for 19 km, of which a 9.5 km-long twin-tube tunnel (T13) tunnel from Narkota to Sumerpur along with a railway station yard at Tilani in Rudraprayag district of Uttarakhand.

Therefore, it also needs to execute the 45 cross passages. As a whole, in this package, the MEIL is executing 27-km-long tunnel works, of which 13.5 km is the main tunnel and 13.5 km is the escape tunnel. Currently, 5 km of tunnel works and 10 cross passages have been completed. A 1,200-strong workforce is involved in work day and night.

Safety of the Workforce
The MEIL’s workforce is the heart of the project, and the safety of these frontline workers is of utmost priority for the company. In the Char Dham Railway Project, work is ongoing in hilly terrain and difficult circumstances. Safety comes first, and at the site premises, the company has arranged safety & precautionary sign boards and equipment to resist tunnel hazards. It has laid electrical safety lines to avoid electrical shocks. While blasting, the safety supervisors and engineers take utmost precautions. They have installed Vibro Meters, Blasting Alarms, Hooters etc., for the safety of the workforce. In addition, air shafts have been established to provide fresh air and oxygen into a tunnel for comfortable breathing inside the tunnel. Oxygen meters and equipment to identify dust percentage in the air are also installed. In addition, the sites are equipped with a first aid centre and an ambulance. Besides providing a comfortable stay and healthy hygiene food, the company provides insurance for its labour workforce, engineers and staff.
In 2020 the RVNL called for tenders to construct the 125.20 km single-track railway line Rishikesh – Karnaprayag Railway Tunnel project in Uttarkhand with 12 stations. The project is considered national strategic and is tracked on the Central Government’s PRAGATI (Pro-active Governance and Timely Implementation) portal.
The broad-gauge line route from Rishikesh to Karnaprayag will have 35 bridges, 17 tunnels, and 12 stations (Rishikesh, Muni Ki Reti, Shivpuri, Manjilgaon, Sakni, Devprayag, Kirtinagar, Srinagar, Dhari, Rudraprayag, Gholtir, Ghauchar, and Karanprayag). These places are important concerning the devotional activities. It will also have other formation structures across Dehradun, Tehri, Rudraprayag and Chamoli districts of Uttarkhand. When ready, it will reduce the travel time between Rishikesh and Karnaprayag from 7 hours to just over 2 hours.
In addition, it will improve connectivity to the Char Dham shrines of Yamunotri, Gangotri, Badrinath and Kedarnath in the Garhwali region of the Himalayas. As a result, tourism, adventure sports, trade and transport will be boosted. It will also strengthen and ease military operations for the defence sector.
Why the rail line
The Char Dham Yatra is considered one of India’s most prominent pilgrimage tours. However, travellers and pilgrims must travel through narrow ghat roads, always prone to mud and landslides due to frequent rains. Therefore, the lives of people travelling this route are always at risk. Sometimes traffic will be held up for long hours and days. This rail route will ease travel.
