Continuous heavy rainfall in Himachal Pradesh has once again brought the UNESCO-listed Kalka-Shimla heritage railway line to a grinding halt. A massive landslide between Koti and Kanoh stations buried large stretches of the track under mud and debris, forcing authorities to suspend all train services until September 5. The disruption has left thousands of daily commuters, as well as tourists, stranded during the peak monsoon season.
The line, commissioned in 1903 and spanning 96 kilometres through the Himalayan foothills, is celebrated for its 102 tunnels, 988 bridges and nearly 919 sharp curves. However, it is also one of the most vulnerable railways in India, repeatedly battered by monsoon-induced landslides. This week’s incident is the latest in a series of natural calamities that highlight the fragile condition of transport infrastructure in the hill state.
The human cost of the ongoing landslides has been grim. In Junga, 35-year-old Virender Kumar and his 10-year-old daughter were killed after their home collapsed under sliding debris, while in Kotkhai’s Chol village, a 70-year-old woman, Kalavati, died when soil from a hillside buried her house. Officials from the State Disaster Management Authority confirmed that at least three people have died in Shimla district alone.
The landslides have not only disrupted railway operations but also crippled road connectivity. As of Monday evening, nearly 788 roads, including 15 national highways, remained blocked across Himachal Pradesh. Traffic on the Shimla-Chandigarh highway slowed to a crawl, while several rural villages were completely cut off. Electricity and water supply in many areas was also hit after falling rocks damaged power lines and pipelines.
The disruption of the Kalka-Shimla line is particularly significant because it is a vital economic and cultural lifeline. It ferries over 800,000 passengers annually, including office-goers, students, and tourists flocking to Shimla. With trains suspended for several days, local businesses, hoteliers, and transport operators are bracing for heavy losses.
According to the Indian Meteorological Department, Himachal Pradesh has already recorded over 1,100 mm of rainfall this monsoon, nearly 30 per cent above the seasonal average. Districts like Solan and Shimla have been on red alert for multiple days due to the risk of flash floods and landslides. Officials fear that further downpours could extend the suspension of railway services beyond September 5.
This is not the first time the heritage track has been hit. In August 2023, unprecedented floods washed away sections of the railway near Solan, leaving a bridge dangling and services suspended for weeks. The repeated damage has raised questions about the long-term sustainability of the line, even as crores of rupees are spent annually on its repair and maintenance.
For now, railway crews equipped with earth-moving machines are working round the clock to clear debris from the tracks and stabilise vulnerable slopes. However, experts warn that with the increasing frequency of extreme weather events linked to climate change, protecting mountain railways like the Kalka-Shimla line will require long-term structural solutions rather than ad-hoc repairs.
