The Indore-Budni New Railway Line Project has reached a notable tunnelling milestone as Rail Vikas Nigam Limited (RVNL) reported significant progress in underground excavation. Work on Tunnel two has advanced to 500 metres of total underground excavation while Tunnel one has recorded 108 metres of progress. The achievement forms part of a broader push to enhance rail connectivity between Indore and Jabalpur and to support regional economic growth. According to project data the 500 metres of excavation in Tunnel two comprised 265 metres at Portal one and 235 metres at Portal two. Tunnelling operations combine mechanised and conventional techniques adapted to local geology and hydrology and crews are executing concurrent face advances to maintain schedule. Temporary support structures and muck removal systems have been installed to facilitate safe access and efficient material movement. Tunnel two spans 8,640 metres and will be the longest railway tunnel in Central India when completed, while Tunnel one measures 1,160 metres. Because Tunnel two exceeds three km in length an 8,640 metres long escape tunnel (ET) is being constructed parallel to the main bore in accordance with Railway Board guidelines to ensure passenger safety and emergency egress. Ventilation shafts, drainage provisions and safety chambers are being incorporated into the design at strategic intervals. Tunnelling is being carried out using the New Austrian Tunnelling Method (NATM) and other advanced techniques to contend with complex strata and water ingress. Project engineers reported steady progress despite challenging conditions, citing technical planning, continuous monitoring and adaptive support installation as key enablers. The workforce has maintained round the clock operations under strict safety protocols to sustain momentum. On completion the Indore-Budni line is expected to shorten the route by approximately 68 km and to improve passenger convenience while boosting freight movement, logistics and regional trade. Work across bridges, viaducts and ancillary infrastructure is progressing simultaneously to meet the project timeline and to ensure integrated system readiness.
