Before replying to this answer, I want to share some history. Gondwana Express started in Mid 90 and at that time its name was Mahamaya Express ( JBP bound). After that Its name was changed to Gondwana Express. reason for the same being if you see Both Jabalpur bound and Bilaspur / Nagpur ( Initially it was Nagpur) Bound covered Gond Region, so it was renamed to Gondwana Express. In 2013 when 22181 Started it was not given Gondwana name just to avoid the confusion.
