Bus Vs Train conflicts are everywhere, Coimbatore has around 80+ buses to Bangalore , Ernakulam and Kannur has a sizable population working in Bangalore but I have neither seen Kochuveli express being empty nor Kannur exp . Kochuveli exp atleast has big names like Thrissur, Ernakulam , Alappuzha , Kollam apart from Coimbatore. For Kannur , it has only Calicut and Palakkad.
