Kolkata’s Purple Line Project to be Completed by 2028-2029

The 14 km Purple Line in Kolkata is slated for completion by late 2028 or early 2029. Tunnel-boring machines (TBMs), manufactured by Herrenknecht in Germany and assembled in Chennai, are expected to arrive in December 2024, with tunneling set to commence by March 2025.
Progress on the Esplanade station received a significant boost with the defence ministry's approval to relocate the BC Roy Market. Most of the 300m x 40m station box will occupy the current market site. Following the approval, Rail Vikas Nigam Limited (RVNL) has invited a ₹19 crore tender to build a temporary structure at the Mounted Police grounds to accommodate 528 traders.
