If you quite frequently travel by trains, you would see officers wearing a paramilitary uniform and orange beret around. No, it’s not Brimob. Few Brimob or Mobile Brigade Corps personnels (with blue beret) often guard trips on railway too. But not as much as Special Police Train or so-called Polisi Khusus Kereta Api (Polsuska) a.k.a. Orange Railway Police (ORP).
