At present WAP-5 has entered KGP - HWH section fewer times whereas KGP - BBS is seeing a regular/occasional run with WAP-7 with Utkal Express.
SRC it self has many WAP-4's, along with VSKP's new WAP-4's n old WAM's which are serving most of the trains in the sector.
Until few locos are retired, SER doesn't see the need of next generation locos, and also til Railway Board discusses with the ELS authorities.

WAP-4's are doing commendable job than the new kids, though new kids are just for acceleration and nothing else.
