Is this congestion effect for these trains? No, a BIG NO for that. 14055 BP Mail departed from Naini at 19.50, 12801 departed 20:06 from KCN, and 12397 departed 20:20 from KCN consequently. Now see the arrival status at ALD 14055 at 20:39, 12801 at 22:03 and 12397at 22:30.
This is not a congestion, this is a complete carelessness of ALD controller.
