It is running with two locos from TPJ - MQ. Loco will be attached at the rear once train arrives TPJ. That will be leading till NMJ and arrived at platform 3. (the loco from CBE will be still at the back from TPJ - NMJ) post which, pilots walk to the other end and take charge at the loco at the other end (the loco which was leading from CBE - TPJ and was back from TPJ - NMJ). Within that gap, MQ - TPJ DEMU will be arriving and departing NMJ at platform 1. After this, chemmozhi departs towards MQ. Some times, at pf 2, TJ - KIK DEMU arrives and departs meanwhile (this is not very common though, generally TJ - KIK DEMU and TPJ - MQ DEMU crosses at SMM).
please wait...Translate to EnglishTwo trains running together from TPJ to MQ. One train will have an engine attached at the back in TPJ. This engine will lead the train until NMJ on platform 3. The engine from CBE will still be at the back from TPJ to NMJ. After reaching NMJ, the engineers will walk to the other end and take control of the engine at the opposite end. In the meantime, the MQ to TPJ DEMU will be coming and going at platform 1 in NMJ. Then the Chemmozhi will leave for MQ. Sometimes, at platform 2, TJ to KIK DEMU arrives and leaves during this time (although it's not very common. Usually, TJ to KIK DEMU and TPJ to MQ DEMU pass each other at SMM.)
