According to https://www.sfmta.com/stops/church-st-27th-st-13998, this stop has been discontinued. Instead there seems to be a stop at Church & 28th St.
Could someone local, please, verify?

One direction of the 48 bus takes a different route, via Castro now

Unable to answer "Is there a shelter at this stop?" for node/6935489253 via StreetComplete 49.0:

There seem to be too many transit stops mapped here. There are 2 along the tracks, one on each side. And 2 street stops on Duboce St on opposite sides of Noe, for the late night buses that replace the trains. And that's all.

Market Street is oneway frome Main St to Steuart St.
Placing a note here so locals can verify it and remap it, as I am afraid do broke some relations.
