NSP express be overtaking Amaravati express based on timings. Why can't it be scheduled earlier, like at 7:30, and Amaravati at 7:40, instead of making it a hassle on the double track.

Yeah, because Amaravati LPI-NS came late, it got squeezed into its old time slot, I guess.

Nah, this name can't be added 'cause it ain't local or commonly known as Chinna Ammu. It's just the railfans who came up with this name. Ya see, we got two Amaravatis running on the same route, VSG SHM and UBL BZA, so to avoid confusion, the railfans named 'em differently. VSG SHM is called Pedda Ammu and UBL BZA is called Chinna Ammu.

Nah, no need for that. This ain't the real deal, just a nickname.

Hell yeah, you got it, bro!
