I guess I am ignorant as to the meaning of differences in the length of the train number. I was just specifically looking for an early morning departure and thus earlier arrival into Shanghai to maximize my time in SH. The schedule I saw indicated that these were amongst the earlier arrival times in SH.
I thought these were arbitrarily assigned train numbers for id purposes only. The letter (G) I do understand the meaning of (G being the fastest trains right now).
I would certainly appreciate your guidance on this. Thank you!
