It can run MMR by WCAM but this may lead to:
1. Extra long stoppage @ IGP
2. From IGP, it again will get Electric Loco, which again will need to be changed @ MMR, adding few extra idle time!!
If diesel been provided @ IGP, it will remain idle for 16-17 hours!! Further, entire stretch of this train dont suggest any Loco Shed...
more... in between & when it gets Loco from Mumbai/Pune, then for better arrangement, it get run till Mumbai. Further, Janshatabdi too run with Diesel Loco, for the same reason!!
