If so many sabarimala specials could be operated from Kollam Junction,I see no reason why 13351/13352 Dhanbad express, 16042/16041 Chennai Express could not be extended to Kollam.If these trains are extended then it would bring much relief to the passengers especially in the Allappuzha-Kayamkulam Stretch.Also the daily commuters from Ernakulam will get enough benefits too.
