Dear Sir , U can take the MYS-TN express upto MEJ..in MEJ the TCN passenger waits till the express comes , only when the train is 2-3 hrs late , the passenger proceeds without waiting..that is tooooo rare..so dont worry..happy journey..TN station is out skirts of the city as it is not properly connected with buses , infact no buses from TN rly station..Only autos and that too lot of charge if u r not local person..better take the TCN passenger from MEJ which reaches TCN by 1 pm...
