Thats why I am saying this because this one doesnt get into VSKP and passes through DVD so the primary loco gets to HWH. Other than that only Aurobindo exp can bring a LGD P4 to HWH. Actually there so many P4's of HWH,SRC (over 150) that very very few trains get any other link of P4's on in case of P7's you can trace 1 or 2 GZB P7's. Never saw ED/RPM P4 in here too !!
