See I can't say on what basis 100% electrification is decided. I live in TN and their were many routes before NDA came to power which were diesel. After Suresh Prabhu came and he decided to electrify the routes then immediately the tenders were passed for electrification of Erode-Karur-Trichy and Salem-Karur-Dindigul via Namakkal. Second was Trichy-Karaikal. 2 are being done by RVNL and that too at good speed Villupuram -Trichy MainLine . Banagalore-Omalur. Now still many lines are there in TN like Sengottai, Pollachi, Palani,Rameswaram. If they want to go for 100% electrification then they should be electrifying them also. Plus there are many lines in North East like Agartala, Silchar. Who knows what does 100% means. We would only be knowing when next budget comes.
