The MTA is running a trainset of R1/R9 cars on the 6th Avenue Line on Saturdays during the holiday season. I have a number of interior and exterior shots but will try to get a few more before doing a lengthier FNY page.
Here’s the schedule if you want to catch one:
The Holiday Special R 1/9 train will run on Saturdays this year from Nov. 26 through Dec. 24. The trains will leave Second Ave. at 9:58 a.m., 11:37 a.m., 12:57 p.m., 2:27 p.m. and 3:57 p.m. and make local stops to Queens Plaza. Planned departure times from Queens Plaza are 10:43 a.m., 12:13 p.m., 1:42 p.m., 3:13 p.m. and 4:43 p.m.
The Chicago Transit Authority also has a tradition of running holiday specials, which are more spectacularly decorated.
