BMT 1.
On Sunday, July 10, 2022, the NY Transit Museum ran it's Beach Bound: Coney Island nostalgia ride, with a train of R1-9 "Arnines" and BMT AB Standards making the journey from 96th St to Coney Island via the Brighton Line. Knowing this was the route, I of course went to my new favorite scene along the whole line, Avenue H!
R9 number 1802 (Pressed Steel Co., 1940) was the lead motor on the southbound run, leading five other Arnines and three Standards.
