As seen above, the metrolite’s civil structure will have 2 underpasses (short cut & cover tunnels displayed in aqua) at the Ring Road – Mayapuri Road and Mayapuri Road – Jail Road intersections.
Besides an approximately 4 km elevated viaduct (displayed in purple) between Tihar Jail and Dwarka Sector-2 stations, 5 small elevated viaducts will be built at or near Kirti Nagar, Mayapuri Bus Depot, Dwarka Sector-7, Dwarka Sector-8 and ECC Dwarka.
Bids for the design, supply and maintenance of 22 3-coach standard gauge Metrolite trains for up to 15 years were invited in early January 2020. Later in the month, the DMRC issued a corrigendum bumping up the number of train-sets to 29. Due to the disruption caused from the COVID-19 related lock-down, the last date to submit bids for it has been extended to June 24, 2020.
Metrolite trains on this line will run mostly at-grade (ground level) on dedicated / fenced-in corridors and act as an excellent feeder to the Delhi Metro system with interchanges planned at Kirti Nagar (Green Line), Mayapuri (Pink Line), Dabri Village (Magenta Line) and Dwarka Court (Blue Line).
More system & project information can be viewed on the Delhi Metrolite info page I created in March. Going forward, project news & construction updates will now be tracked through a new Delhi Metrolite category.
