Yes. BGP has one more option in 13403/04 Vananchal Express. Though it takes a longer route, the advantages of Vananchal Express are, it being daily and having comfortable timings at both source and destination in either direction.
On the other hand, the schedule for 18604 GODA - RNC Express is good for BGP pax. But for 18603, the timings are a bit uncomfortable. Even the departure time at RNC ensures wasting half day.
