It is not the Typo.. Aurangabad is a city in Bihar 90 Kms from Gaya, and it is one of the two boarding points for the Gaya - ANVT bus, the first being the Gaya town itself.
Nowhere the card says 26 hrs as journey time. It is merely saying 12 PM is pickup time at Gaya and 2.30 PM is pickup time from Aurangabad. Are you confusing it as 12 PM - 2.30 PM next day as journey time??
