The second corridor of the Regional Rapid Transit System between Delhi and Gurgaon has begun pre-construction (Shahjahanpur-Neemrana-Behror). Construction on the route will start as soon as the Center gives its approval. According to a representative of the National Capital Region Transport Corporation (NCRTC), the organisation responsible for carrying out the project, the detailed project report has been approved by concerned state governments and is under active consideration by the central government. The Delhi-Ghaziabad-Meerut first priority corridor is currently being built and will be operational by 2025. Nonetheless, it is anticipated that the 17 km priority segment between Sahibabad and Duhai will be operational soon. According to officials, pre-construction work for the second corridor is underway, including the shifting or modification of high-tension electric wires. Modern tools and technology were employed, then the necessary adjustments and anchoring. Power supply disruptions were kept to a minimum, an official declared. A running motorway was used for the construction, he continued, ensuring no disruption to traffic. According to an official, residents of the NCR should profit from the strengthened utility infrastructure. There will be three phases of the 198 km Delhi Gurugram-SNB-Alwar RRTS corridor's construction. A 107km stretch from Sarai Kale Khan in Delhi to SNB Urban Complex will be built in the first phase. The line would be extended from SNB to Sotanala in the subsequent stage (33.3km). The third stage has been suggested as an extension from SNB to Alwar (57 km). The Delhi-Gurgaon-SNB line, which is 107 km long, would be elevated for around 72 km (11 stations), and the remaining 35 km (five stations) will be built underground, primarily in Delhi and Gurgaon. Once in operating, the corridor should reduce the distance between Delhi and SNB's airport to around 70 minutes. The corridor will make commuting easier for many people because it will put the national capital closer to the region's industrialised districts, educational institutions, and lodging facilities. The interoperable Delhi-Gurgaon-SNB line would connect with other corridors at Sarai Kale Khan, making it easier for travellers to switch between corridors without having to deal with changing trains. The Delhi-Gurgaon-SNB corridor will also be seamlessly connected with other means of transportation in the NCR with the goal of encouraging the use of public transportation an official declared. Phase I of the RRTS includes three priority corridors: Delhi Ghaziabad-Meerut, Delhi-Gurgaon-SNB-Alwar, and Delhi Panipat. According to an NCRTC official, preconstruction activities, such as road widening work, preliminary pile load testing, geotechnical investigation, final location survey, topographical survey, and mapping of underground utilities, are in the advance stage of completion. The official also noted that the topographical survey and final location survey from Sarai Kale Khan to SNB have been completed.
