Salesforce Transit Center in San Francisco opened this week; I went to the third day of revenue service for the afternoon peak buses.
There are many AC Transit coaches with a few LYNX and Greyhound buses on the main level (3).
Included are buses along SamTrans route 398, some of the Muni buses on the ground level of the transit center, and SamTrans route 296 on Middlefield Rd.

Keyboard arrows, a scroll wheel, or swiping left and right will move through the pictures.
There are also buttons to play the slideshow, make an image full screen, and display thumbs on the side.

Nikon D3400 and LG Stylo 3 Plus yielded 420 photos with 6 cropped versions.
