By train it gives us a chance to spend 2-3 days with your loved ones. Instead of flying and reaching in just couple of hours. So, just try with train and you can see south adventures, food in Kerala Express has local touch also.
Very boring because train was late by 15 hours so I suggest not to travel by train. Instead take a flight but if train wasn't late then it could have been a pleasent experiance. I think if we are planning to go from Agra to Coimbatore instead of travelling three nights we should travel by flight.
