During the holiday season, the M.T.A. offered straphangers the chance to ride on vintage subways and buses. The “Nostalgia Train” operated on the M line between Queens Plaza and Second Ave. on Sundays only, from Nov. 30 to Dec. 28, between 10 a.m. and 5 p.m. Kicking things off, swing dancers in period costume performed on the platforms and rode the train. It included subway cars in service on the lettered lines between the early 1930s and mid-’70s and featured ceiling fans, padded or wicker seats and incandescent light bulbs.
