Being a night journey from Mangalore to Thiruvalla, it was a comfortable journey. Catering services are generally not good but vendors in platforms do visit the bogeys. The toilets were not very clean but that was because of the travelling public.
Nice Journey. Train came on actual time. For a day in the fresh air, and a scenic, memorable journey, this is a good trip. A little on the expensive side, make sure you arrive early for your train, as in August there was a long queue. Not to expensive, easy and quick.
Comfy seats on the journey and was amazing with during the hot weather - nice cool breeze while going through the tunnels. Station was clean, service was good.
