The train numbers are 22413/22414. Not sure about the timings, but it appears, this train will have a slower travel time when compared to the 12431/32 Trivandrum Rajdhani, which covers the distance between Nizamuddin and Madgaon in just over 25 hours.
One thing is for sure, this new train like most of the trains on Konkan Railway will have more halts outside Goa. The only Goan halt will be the terminating/starting point-Madgaon.
