Both the trains UP and Down have crossings at almost every KR station in Maharastra.
I don't think you have accounted for that with a buffer... or have you?
If not this train will delayed by hours on the KR section...
The truth is that the KR section is already running more trains than it's capacity. Adding more trains is really difficult till doubling...
more... is done.
Doubling work is going on at a snail's pace.
Because of this reason I feel this train might remain IMG till then.
