Not required let 17309/10 start from VSG. The rake is only moved to SVM on Wednesdays and not on other days. This daily connection existed between Vasco Da Gama and Bengaluru since MG days. Let PNVL people demand a separate train if required.
And 17039/40 is for VSG and Goa not MAQ. There is absolutely no logic in any of your points. If you have any personal vendetta against Vasco Da Gama city let it be known instead of asking for unnecessary things.
