looks like IR turning more cosmopolitan in nature

These 'R' locos are normally rebuilt by DMW (earlier DCW), Patiala. The old Erode (ED) shed livery was similar to the DMW livery and often people get confused. Has happened to me many times. Now, of course, ED's livery has a bright yellow middle portion.

is this a special liveried vaccum braked train? or an air braked rake with a newly approved livery pls. tell me Mr. Apurva

It is indeed a Pune loco. Look closely at the Pune shed logo on the front of the short hood

Is it a Pune or ERD WDM-3A?

the pic's good but WR should have concentrated themselves on pre-coat first,edges should have been smothened and should have tried to match the livery exactly with the LHB rake. i.e for NDLS-BCT Rajdhani

Much, much classier than anything else I've seen in Mumbai. It is good to see they have also gotten rid of the fixation with stripes that they had earlier. Think up some more liveries of this type for WCAM2 locos WR. Vivek, I've got a pic of this loco hauling BCNA wagons on the 5th of November ;-) at Virar

Vivek Manvi, thanks for the clarification. I was actually comparing this pic with the previous 2 pics where the locos have their DC pantos on, hence the confusion.

Karthik, the loco is running under AC not DC wires. The Virar-Vasai-Panvel section has been converted to 25KV AC quite a while ago!!

Looks like the loco is running on AC panto in spite of being within the DC zone. How is this possible? Can someone clarify?
