ME-1 (New York City Subway car)

The ME-1 was a rapid transit car built from 1925 to 1926 by the Standard Steel Car Company for the Staten Island Railway and later also used in the New York City Subway. They were the first electric cars to run in revenue service on the SIRT. They are also frequently referred to as MU-1s or MUE-1s. The 25 cars purchased by the New York City Transit Authority to run in the subway were nicknamed B-29s, a reference to a large aircraft of the same name. This nickname was derived from the cars' large size (67 feet or 20.42 meters) and the fact that the cars had been renumbered for subway service into the 2900's.
