Reader Mike Toppa sent me an interesting little tidbit about the 69th St. Terminal bathrooms: 

The sign pictured here went up last month at 69th St Station. Check out the price tag: $408,692 to remodel the men’s room and the women’s room. My nice large house in a good neighborhood isn’t worth that kind of money. The station’s men’s room is a modest size – two toilets, two urinals, two sinks. Presumably the women’s room is similar, so we’re not talking about large facilities.

The price tag for these bathrooms is astronomical, no doubt. I've reached out to SEPTA for comment, and I'll update here if they have an answer for me.
