If the works are probably going on for electrifications,we can see some electrifications work in coming months like Poles being installed and Wiring being done. The work along side from Tiruchirappalli to Karaikkal,the work is also from Nidamanglam to Mannargudi and Mayilladuthurai-TVR and connected line to VLNK. so the only left main route for electrification is Dharmapuri to Bangalore I hope it gets sanctioned soon.
