Looks like the train left almost empty.. Very short notice given could be the a reason, Train announcement was in the local news only on 12th or 13th Oct and train departure date was 14 Oct. 24 hrs before the departure, ticket available were 470 but 15 minutes before the departure of the trains tickets were available 934 (Curr-Avail.). Capacity of the train I think 18x72. Most inbound new special trains to Goa come full but outbound trains not so full. e.g VSG-NZM Humsafar, MAO-NZM Rajdhani special etc almost empty. If the VSG-PNBE was in the reverse direction (i.e. PNBE-VSG) then it would have also come in full
