How many days, weeks or months its been since these biggies TN, KL, TG, AP made it on or before time to New Delhi ? It looks like no longer these are a priority for NCR and NR zones even Bengaluru, Chennai, Secunderabad Rajadhani and Dutontos are not making it on time. Till Bhopal they are almost on time or slightly delayed and from there every train from southern side is trolled. Increased traffic is the reason ? or something else ? or is it just a common thing which can be ignored ?
