With the inauguration of Tr. No. 16595 from 8th March 2020, I read widely across media that its good news to travelers from Bangalore to Goa. Though the train board has YPR - KAWR - VSG mentioned on it. I guess there is no direct ticket / adv resv available online on irctc website from YPR to MAO. Though I found out from NTES website that the YPR - KAWR reached around 90 mins late to KAWR today and the onward train from KAWR to VSG departed KAWR only after the YPR - KAWR reached KAWR. Therefore, I have a few questions - if anyone can help -

board from KAWR to MAO / VSG
b) Does the same train go further up to VSG or does one have to change train
c) Why is ticket not issued directly from YPR to MAO / VSG
d) Is e-catering available on board?
e) Since its a daily train a Pantry car could have been a boon to passengers both ways.
