WAP-4 Smooth Coupling, Loco Startup | Palakkad SF | MGR Chennai Central

Experience the complete WAP-4 locomotive coupling with the Palakkad Superfast Express at MGR Chennai Central. This video captures the entire sequence, including smooth coupling, locomotive startup and pantograph change. After coupling, the locomotive crew lowers the front pantograph, powers down the locomotive, raises the rear pantograph, and restarts the WAP-4. The rear pantograph is preferred because it provides more stable current collection at higher speeds and helps reduce the risk of overhead wire damage if a pantograph fault occurs. #wap4 #palakkad #mgrchennaicentral
