one thing is very clear all SF trains will only and only run through NOQ,NCB section and the track is being upgraded and equipped to handle high speeds(upto 110kmph).Doubling is going on and will ensure high entry and exit.What APDJ-SGUJ needs is proper intercity travel trains to connect to nodes i.e.NCB,SGUJ.For that that line needs to be de congested.It needs to be remembered that DMUs,I/Cs are the key to this line and some region centric long distance trains can be allowed.
