Dear friend, a few observations for the train:
(1) 150km extra run (3hrs extra time & higher fare) of the tri-weekly train and in return new connectivity to Valsad & Vapi, which is not going to give any significant traffic. No stop at Udhna (ST) is very surprising.
(2) There are many faster trains from Mumbai on the route and no Mumbaikar shall like to board this train.
(3)...
more... Also a wastage of precious terminal capacity of BDTS.
(4) ST/ADI/JDP/Bikaner/Dwarka/GIM/Somnath could have been better terminal station at western end.
(5) Orissa badly needs train connectivity to Rajasthan with Puri-Jodhpur weekly remain jam-packed round the year. So JDP/Bikaner could have been a very good option.
