The Hudson River Railroad's West Side Line ran along Tenth Avenue from its intersection with West Street to the upper city station at 34th Street, after which it veered to Eleventh Avenue; the line was completed to Peekskill, New York in 1849. Over this part of the right-of-way, the rails were laid at grade along the streets, and since by the corporation regulations locomotives were not allowed, the cars were drawn by a dummy engine, which, according to an 1851 description, consumed its own smoke. While passing through the city the train of cars was preceded by a man on horseback known as a "West Side cowboy" or "Tenth Avenue cowboy" who gave notice of its approach by blowing a horn. However, so many accidents occurred between freight trains and other traffic that the nickname "Death Avenue" was given to both Tenth and Eleventh Avenues.
