Passengers travelling on several routes from Chennai Egmore, Puducherry and Tambaram should prepare for delays over the next few days, with the Southern Railway announcing regulation of seven train services.
In a post on X, Southern Railway said the changes are due to a line block and power block for engineering works at Perani Yard on the Chennai Egmore-Villupuram section. The impacted trains will be regulated and delayed en route rather than cancelled.
The disruption covers services including Vaigai Superfast Express and Chennai-Egmore-Tirunelveli Vande Bharat Express and trains towards Thiruvananthapuram, Tirupati, Rameswaram, Kacheguda, Bodinayakkanur and Tirupati.
Vande Bharat, Vaigai Express among affected trains
Train No. 20665 Chennai Egmore-Tirunelveli Vande Bharat Express, which left Chennai Egmore at 3:10 pm, will face an en-route delay of 20 minutes on September 3, 4 and 5.
Train No. 12635 Chennai Egmore-Madurai Vaigai Superfast Express, which has a scheduled departure of 1:15 pm from Chennai Egmore will be delayed en route by 1 hour and 50 minutes on September 3, 4 and 5.
