I often travel from Boisar to Mumbai in Valsad fast passenger Train,Western railways.
There are group of Holligans/regular traveller in the train who force fully retain a sitting space for a traveller who is boarding the train at the next stop.
Its really difficult for a single person/ new person to get a place even if one can see an empty space.
This is a regular picture in this train.
Request you to pls look into this matter.
