Route between anvt and LKO is completely electrified, so it should be hauled by electric loco between ANVT-LKO? Although it has stoppage of 20 min which is enough to change the loco! then from LKO it can be hauled by diesel loco. After run of electrified route LKO-GKP it should be hauled by the same electric loco. Eloco can be TKD WAP 4/7 and diesel loco can be WDM 3A/3D with shed of LKO or GD.
