Explanation –

Statement 1 is incorrect. Udhampur-Srinagar-Baramula Rail Link Project (USBRL) is 272 km-long. The project connects Udhampur to Baramulla. It aims to connect Kashmir Valley with the rest of the country by a railway line. It includes 38 tunnels with a combined length of 119 kilometers. The longest tunnel in the project is Tunnel T-49, which is 12.75 kilometers long making it India’s longest transportation tunnel. There are 927 bridges in total. One of the bridges is Chenab Bridge which will be the highest railway bridge in the world. Indian railway’s first cable-stayed bridge is also being constructed on Anji Khad.

Statement 2 is correct. There are many challenges being faced by the engineering and they developed indigenous innovations to address these challenges. For example, in order to prevent water freezing, engineers have designed double-walled composite insulated water tanks. These tanks have a design similar to thermoplastic bottles, with two walls and a foam insulation layer that traps air. This can keep water in liquid form for 16 to 20 hours, even in sub-zero conditions, ensuring toilets and taps function properly.
