Gorakhpur-Trivandrum Raptisagar Express arrives behind an old maroon colour Arakkonam WAM-4. The train uses the same time slot used by Cochin-Nizammudin Jayanti Janata years ago. It was my favorite train in my childhood days when I used to do trainspotting at the same place with my dad 25 years ago. Ernakulam (Pullepadi), 2004-03-27. By Jimmy Jose.
