Weekend Terminus.
A Queens-bound 7 train arrives at its weekend terminus of Mets-Willets Point station, having just entered the switch to the middle track. Because of the COVID vaccination center at Citi Field, all platforms at the station have been in service, allowing me to check out the Queens-bound side platform that is normally only open for special events.
The other interesting part of this GO was that trains originating from this track had to use the lower level track to access the Manhattan-bound track at 111th St. Thus I added another seldom-used (for revenue service) section to my list of lines I've ridden.
