Here we see a 240th St Set in operation out of Westchester Yard, this time 18261830. These cars also use to be apart of Westchester Yard before they were sent to 240th.

Edit: These cars may be here to replace a set of singles that is currently out of service, due to 1934 replacing 2176 over at 240 St Yard. It’s not confirmed though at this time whether this will be temporary or permanent.
