Yes...After loco upgradation to GZB WAP7 it is mostly getting SRC/MGS WAP-4 as offlink on 2 days of a week...but GZB WAP-4 is never seen even as offlink since then... I think since last 6-7 months(or even more) GZB P4 has hauled this train only twice... Now only Odisha Sampark Kranti is bringing WAP-4 GZB everytime as Duronto's loco has also been upgraded to GZB WAP-7..
