Actually, the whole logic to run North bound trains via shortest route is absurd. shortest route hai definitely but economic feasibility bhi matter karti hai, udhar se definitely nee trains deni chahiye jo useful ho jaise Mumbai/Delhi/Kolkata k liye M/E trains. Is logic se to fir RNC trains ko BKSC shift kardo and run them via LAD-TORI towards North shortest route sabka bhala hoga.
