The NYPD began using horse-drawn police wagons in the later part of the 19th Century to move police forces from place to place. Motorized wagons came into use later, and it wasn't until the 1920s and 30s that the department began regularly using motorized patrol cars. Plymouth two-door radio cars were the standard in the late 1930s and 1940s. By the 1970s, the Plymouth Fury was the mainstay. Black-and-white photos courtesy of the New York City Police Museum.
