More than a decade back image seen here is Wdp4 #20056 hauled 11029 Mumbai Kolhapur Koyna Express at Nira. Now this section is fully electrified.

EMD GT46PAc also known as WDP-4 class in IR, one of the locomotives of Krishnarajapuram loco shed,speeds past Bhilad with Jaipur-Yeshwantpur (Bengaluru) Suvidha express.

Normally the Blue Train is hauled by blue liveried 20Es 20 031 and 20 032, but these are obviously in for maintenance. 20 056 and 20 034 stand in for the regular pair.
