7621 and 7624 from Flatbush also did runs on the D99 yesterday too so maybe it might be split between Ulmer Park and Flatbush if there's ever a gap in service on the route
6030 and 6032 are back at Flatbush from Casey Stengel after being there for the summer
6111 (summer loan to CS from MJQ) and 6115 MJQ are also apparently at Tuskegee for some reason
7635 Flatbush is in Ulmer Park as it ran the B64 earlier today
