The last crossing pictured above
is this one. Other than the LEDs being put in the lights and another WCH e-bell replacing the Safetran mechanical bell on the northern (yard lead) track, and adding the blue DOT signs, it's basically unchanged from 2010.
It doesn't look any crossings from Beloit are on the site. I actually took a photo set of Prospect Street the last time I was there in 2021, along with more photos this past Sunday (it hadn't changed noticeably in two years, other than the lights on the southern signal being aimed more toward the left to be better visible to traffic approaching on Colby Street, kind of weird there isn't a pair of side-facing lights here). It's by far the most untouched classic setup in the area, although there are a few others like the eastern crossing on Colley Rd. with incandescent lights and a mechanical bell.
Note that with the bridge across Turtle Creek going into Illinois out of service, the only road traffic through the Prospect Street crossing is going to and from a handful of industrial and commercial businesses along Colby Street.
