sir, winter is also the season of off-links across IR, TN was spotted with HWH WAP-4 MGS WAP-4, CNB WAP-4 (ICF era) during these times, LGD with TN is pretty common i can say. TATA WAP-7s and GMO WAP-7s both handled TN in the past. Now that EOG is a must for all long distance trains hence the trip shed must have sent whatever available..lol
