Kalka-Shimla Railway: UNESCO raises concerns over changes to heritage structure

The UNESCO heritage team has raised objections regarding the changes in the original structure of the Kalka-Shimla railway track. These changes happened during repair work carried out after heavy rains and landslides between 2023 and 2025. A survey report from November 2025 has now been submitted to the Railway Board for clarification.

Why did UNESCO object to the repair work?
The UNESCO team found that several damaged sections were not restored to their original heritage look. Instead of using traditional wood and stone girders, the railway used steel and iron girders for rebuilding bridges. A major example is Bridge number 800 at Summerhill, where a 20-meter iron girder was installed. Additionally, new bricks were used to build retaining walls instead of the original old bricks.

रेलवे ट्रैक को सबसे ज्यादा नुकसान कब हुआ था?
अगस्त 2023 में भारी बारिश और भूस्खलन के कारण 135 स्थानों पर भारी नुकसान हुआ था, जिसमें समरहिल और जुतोग स्टेशनों के बीच की लाइन बह गई थी।
