11. NYC Subway
Susie decides that taking cabs eats too much into the money they’re making on the radio spots, so they take the subway. The teal interiors of the vintage subway car match perfectly with the Pursettes and Midge’s coat. Based on the signs, they are on what is now the F line, which makes stops at Houston-2nd Avenue and Forest Hills, Queens.
Filming of vintage trains, of which many are on display in the New York Transit Museum, are done in conjunction with the MTA. This specific train appears to be the type of Bluebirds that were used for the World’s Fair train (or a classic Redbird given a full makeover for this shooting). Though the Bluebirds are already light blue on the outside, for The Marvelous Mrs. Maisel, it looks like a teal paintjob and teal upholstered seats were added.
