why all sorts of nautanki,
filling forms, then informing them (they have easy approach to rumors but not for factual news), screening at stations, social distancing on platforms and in train. Let them go the way they want to. They will/are dying of hunger at the places they are at now and bags full of ration is waiting for them at their native places.
btw, didnt hear any Bangladeshi or Rohingya migrants asking for such a facility to drop them to their native places. Who is feeding these millions of illegal immigrants
