All these trains are operated with 16/17 coaches.
So additional AC 3 tier coaches shall be added without reduction in Sleeper class coaches.
Indian Railway asked to run ICF 24 coaches / or 22 LHB coaches.
So further 6 to 8 coaches shall be attached in these trains or Sectional coaches 6 No's shall be attached in Pune...
more... to Chennai Sector in these trains for the benefits of the passengers. Mostly for Pune to and fro reservations are not available and so Kalyan ticket has to be bought with boarding at Pune.
So sectional coaches between Pune and Chennai sector one is feasible one .
Moreover tilldate ,no direct trains are operated between Pune Mini Metro and Chennai Metro.
