No harm in Changing the Train No By the Way.
But there are ways to convey things.
.
Why such unwanted statements if you really want to only point out a mistake "How can a noon passenger from Bangalore to Tumkur be overtaken at Golhalli by a Hubli JanShatabdhi and Chalukya express that starts from bangalore at morning time itself?
Was...
more... jan shatabdhi too late or passenger left 20h late/6h early?".
.
Why can't you just say that "please verify the train no once". This sounds pleasant and very good.
.
What you did i m not saying it as wrong. I m just saying this can be conveyed in a way better way. So please understand. Happy blogging. :-)
