There is no Fuelling facility for Loco & EOG anywhere till Karwar in KR. No watering facilities too. When 12133/34 was introduced & was running till Karwar - Watering was done there, later when extended till Mangaluru Jn, Watering facility remains unused.
So sent to Madgaon & also for Cleaning Activity. There is/was plan to Extend it till Madgaon, when 2 New Platforms at Madgaon gets completed. Don't know what's plan now.
