The first one is eid prayer, not a regular one. Every muslim practising/non practising comes out to pray in eidgah on that day because it's sunnah to do so. Lack of space is an issue everywhere that's why we perform it in beach here in Calicut. But out of all places why would anyone pray on a railway track which is extremely dirty and full of filth.not to mention blocking a train and the inconvenience caused to the fellow train passengers.
Second one, the security personnels could have just driven them to prayer hall instead of making a fuss about it.
Third one is totally unnecessary. Even though there is no prayer hall in a railway station(do they?), no one have the right to own a part of railway platform.
Correction- it's not eid, it's the last friday prayer of ramzan which is also auspicious for us.
