A view of the O-K Line in Jefferson Parish around 1923. The regular interurban car is pulling three trailers that were formerly in service in Brooklyn, New York. These trailers were often used during times of high patronage, such as when horse racing was in season at the Jefferson Park Race Track near Shrewsbury Road.
