DoesnтАЩt matter what kind of train, the Castlerock-Kulem Braganza Ghat section will always take 1 to 1.5 hrs to cover due to the steep gradient, and the brake testing halts while descending the ghats. Also the Dharwad-Londa-Castlerock section is also full of sharp twists and curves, once again restricting the max speed.
Only from SBC to UBL we can hope that someday a train could be capable of covering it in 5 or 5.5 hrs. Then UBL to CLR via Dharwad/Londa could take around 2 hrs minimum, CLR to QLM around...
more... 1.5 hrs including time to attach and detach banker locos, and QLM to MAO around 45-60 mins atleast, to account for some slack.
Total time: around 9.5 to 10 hrs minimum for this route
