WDM3D is good for speed and hauling 24 coaches. Before electrification in VM-MDU sector 3D's only used for Kanyakumari, Muthunagar, Pandian, Nellai and Podhigai. After MDU no train goes in high speed, they passing only in normal speed. My question is were and when this photo is taken? becuase this photo shows tracks in no-pole area. Currently no pole area in south tamilnadu is available in VM-MV-TPJ route, TPJ-RMM route, MDU-RMM route, VPT-SCT route. Guruvayur won't use any of this route!!!
