12622 Tamil Nadu Express which earlier had one of the best on time arrival/departure record is daily getting delayed at Nagpur due to Jaipur-Chennai/Bangalore/Coimbature Express. Tamil Nadu is not allowed to overtake these train before Nagpur. Even sometimes it is not allowed to overtake Bangalore express at Ballarshah. This is tainting the reputation of TN Express.
I have been fan of TN but for last 3 years, this is hurting me. I dont know why railway is not rescheduling JP express to be overtaken before nagpur. I request railways to reschedule TN or JP express :(
