Well I won't take it as a wrong statement... and I agree to ur point that by looking at the zone we could find out that.. yes this is from this src to dest... like WR means Mumbai Gandhinagar Capital... but after 5th VB which is Chennai Mysuru VB, it's converted to IR... and I think it's not that difficult to identify which VB train is running cause after the above mentioned one, 6th is under SECR and 7th is under ER... but yes as we increase more VB trains and have IR it would get difficult..
Since...
more... we know that next VB is being launched in South India but under ECoR zone and since that section has only 1 VB train we could tell that it is VSKP SC train but as it increases it would be difficult... so let's see if later they plan to convert to different zones....
