See, that was kinda cool! You can see that and more counts on the updated roster in the link in my signature.
Me and two friends visited Castleton Depot and while being asked by a MTA worker there why we were there, I asked about the only Orion V that was there (6000), and she said that's being preserved and refurbished for the museum fleet. The other Orion V's in CA are gone.
And also, weren't 174 & 180 accidentally scrapped?
So I was right in seeing 9503 that night, and seeing 9580 in the day! What's the need for mobile swings? Doesn't Fresh Pond need those buses, or did the NG's from Charleston cover that?
9580 with an ENY sticker, is the party (relief/break) bus at Rockaway Parkway. Was there last night (thought it was 9503 at first). A paper sign in the window says "6AM HOLD".
