Even I have seen such a Barbie Doll Liveried WAM - 4 Loco of Bhilai Shed which had brought in the Akal Takht Express from ASR Side , way back in 2004 . It was an Off - Link as GZB WAP Locos serve on that route usually . These "bechara" WAM - 4 Locos are the Last Batch of WAM Series manufactured by CLW Unit and are nowadays used to haul Normal Non - Superfast Express Trains .
