Few points I noticed about this new train 19063/Udhna(Surat) -Danapur(Patna) Bi-weekly Express :
1) It's a bi-weekly train which going to run on Tuesday & Saturday. Whereas 19047/Surat-Bhagalpur (bi-weekly) also runs on Tuesday & Saturday.
2) It will start in morning from Udhna at 7:20 am whereas 19047/Surat-Bhagalpur also departs in morning from Udhna at 9:44 am.
3) It will reach Danapur at...
more...

13:35 whereas 19047 reaches Danapur at 12:26.
4) Travel Time is 30 hours 15 minutes whereas 19047 takes 26 hours 42 minutes between Udhna to Danapur.
5) It has 16 intermediate halts whereas 19047 has 24 halts between Udhna to Danapur.
6) Both are Express Type, not SuperFast type.
.
7) As RB Officials said that No new trains will be passed via the busiest route ALD & MGS in order to reduce HUge Delay. BUt this new train 19063 touches both the Junctions.
They could have passed it via Katni-Singrauli-Chopan-Chunar- Mughal Sarai.
8) It will be overtaken after MGS by 19047 as per TT of both trains.
9) They could have passed via Grand Chord line to give direct connectivity of Surat to Bhabua-Sasaram-Dehri- #Gaya- Jehanabad. Only 90 KMs would have been extra.
10) 19057/Udhna- Varanasi weekly Express has huge vacation berths (Avbl 201 in SL, Avbl 10 in 3AC, Avbl 23 in 2AC) for 28th August 2015 [i.e status is JUST 6 days before journey] (Similarly for Fri-Sep 04 : Avbl 254, Avbl 29, Avbl 23 ). So WR Zone could have easily extended this train upto Danapur.
