Hi, I thought'd i'd make a separate post on hexbear for HSR/CRT. The main china summary post is on lemmygrad if yall wanna check it out.
I rode the HSR 3 times total, and I've said this a couple times, but the biggest compliment I can give is my lack of complaints.
The experience was super smooth, very quick security check and quick ticket check into a very smooth train ride. I will say I really do not like how loudly people speak on calls but that is more of an old person thing and noise canceling headphones do the trick.
As for the Chongqing Rail Transit, the CRT was probably the cleanest metro i've ridden on before(I've only been on the NY subway and the Toronto TTC before).
Pricing was from 1-7 yuan(0.15-0.95 dollar)
There was communist imagery(only on line 5 though)
images aren't uploading so i'll try and edit with them or add them to the comments
There were different AC settings on different cars(a lot of older chinese don't like too much AC), and overall very good experience. Not too notable either except cleanliness which I think is a plus.
I am ashamed to admit that the merch i got on my china trip mostly consists of... checks notes... hatsune miku, jjk, and sanrio merch.... oops.
