The fantastic curves begin after Palghat and the Erode WAP-4 hauling my train takes all of them with ease. The only disappointing thing is my train never went anything above 90 kmph and once we entered Kerala we were down to speeds of around 65 Kmph or less. Speed limits all the way not allowing anything above 50 kmph. Ottapalam, 2003-12-14. By Sandeep Mohan.
