Etymonline
Word Origin & History
trolley
1823, in Suffolk dialect, "a cart," especially one with wheels flanged for running on a track (1858), probably from troll (v.) in the sense of "to roll." Sense transferred to "pulley to convey current to a streetcar motor" (1890), then "streetcar drawing power by a trolley" (1891).
