WFWA has four channels total, three of which air Arthur! I used to be able to receive WBGU over-the-air back in the days of analog television...
WFWA was one of the stations that aired Wishbone (up until a couple years ago) and Mister Rogers (up until it was replaced by Daniel Tiger last year). I've read online that some changes are coming to PBS Kids this October. The new show, Peg+Cat, premieres, and Barney is planned to be replaced by a new season of Thomas And Friends. Also, the "PBS Kids Go!" branding is supposed to be phased out by then. Actually, I already noticed season 16 episodes of Arthur no longer than the "Go!" bumpers at the end of the show.

Looks like many PBS stations opt to simply go with the national PBS feed's schedule nowadays, which for some reason has TONS of repeats during the day...
