Giving stop itself has reduced lots of superfast trains to passenger trains speed. I think there should be some differentitation between exp, superfast, passenger trains. Mangala exp stops at Pattambi, kerala ex stops at otp. These are superfast trains in itself with good speed outside kerala
All day trains towards TCR/SRR stop at otp (Intercity and DHN-Allp being exceptions). I feel some trains should be left out. This will lead to more demands and further slow donw trains within kerala
