As we mentioned over the weekend, the MTA rolled out vintage "Low-Voltage" trains to celebrate the 110th birthday of the NYC subway system. And there's a "Low-Voltage" train running today, too, because the trains started running on October 27th, 1904!

From 11 a.m. to 3 p.m., a vintage train will be traveling (on the 2/3 track) between 42nd Street-Times Square and 96th Street; the MTA says, "It departs 96 St at half past the hour." And from the MTA:

October 27th, 2014 marks the 110th anniversary of the subway system. The first train ran north from City Hall to 145th Street and Broadway. The system that now benefits 5.8 million daily customers sprang from a single line that didn’t leave the confines of Manhattan.

The system has grown into a four-borough operation that each day moves more than double the population of Chicago. Trains running along 24 lines feed the City’s schools, businesses and recreational venues. New York could not be the 24/7 City it is today without the MTA New York City subway and the system will continue to nurture the City’s growth far into the future.

Here are photos of what yesterday's train rides, on two different trains, looked like.
