CR and SCR are chockers for AP. SCR has an excuse of having more stops. But CR delays this train too much on both directions. If there is a slight delay, they would hold this train for Vandebharat OT and then SBC Raj and Telangana follow closely behind. Controllers in CR are willing to hold this train for all 3 OTs to complete even though 12723 arrives 2 hrs later in NDLS. Most foolish ppl do their jobs in CR.
