Erode WAP-4 with the Tea Garden Express. This loco does not go back with the Tea Garden, but will go to New Delhi the same day with the Kerala express. It has come with the slowest train on Erode - Ernakulam route with 28 stops on the way. Now, it will go with the fastest, with only 5 stops!! Ernakulam Jn., 2003-12-23. By Jimmy Jose.
