Beyond SRR-PGT very few only will use 16344.But Just One Month has gone,as time goes on to ERN/TCR will also fetch pass to and from MDU/DG. Minimum 1.5 hour speed up will be done by next year. Which means it could reach MDU around 11.30 which is almost similar to GUV-Chennai Circuitous Route.
As I told, this train itself got extended mainly for SRR/PGT/POY/PLNI-MDU-POY/PLNI-PGT/SRR as they don't have any other rake for running any train in PGT-MDU stretch.
