Hey before electrification of BSB LKO route via RBL and electrification after LKO why did this train entirely run with an diesel loco end to end ? Why not traction change at LKO and get an electric loco towards its destination ?????? OR WHY DID THIS TRAIN RUN VIA BSB SLN LKO route ??? AND THE LKO CNB ANVT ROUTE OR THE BSB PRYJ CNB ANVT ROUTE?????
