Yesterday I was returning to Chennai in Silambu Express from Karaikkudi. Pallavan Express crossing in Pudukottai. Saw 12605 - Pallavan Express with very few people travelling in it. Only 2 or 3 people were travelling in each and every coach. I think this train unnecessarily extended upto Karaikudi. No profit due to this. SR can retain this train upto Trichy or allow some few coaches to Karaikudi by detaching coaches in Trichy like Nilagiri Express.
