When they propose extentions they should see that round trip is 4000km for running LHB rakes in future.if thus point is taken when planning CDG and DDN/UK are best locations. As both are congested now and require additional PF/lines for stabling. But the proposal to Jammu is keeping idle for 20hrs against 8 required taking LHB into account. Or they should have changed the timing such that it arrives back to HYB by 1300 having 10hrs for PM.
