Was drafted to post for Railfain. Posted later in appropriate section. Unfortunately, can't be deleted from here.
Halt for this train is legitimate. It's neither a Duronto or Humsafar or a Rajdhani class.
Did they really divert the train? What was the original route and/or origin/destination?
That's what I wrote earlier, Entry# 5027737. Skipping Barrackpore (BP) was the point.
