The IRT Jerome Avenue Line, also unofficially known as IRT Woodlawn Line, is an A Division New York City Subway line mostly along Jerome Avenue in the Bronx. Originally an Interborough Rapid Transit Company-operated route, it was built as part of the Dual Contracts expansion and opened in 1917 and 1918. It is both elevated and underground, with 161st Street–Yankee Stadium being the southernmost elevated station. The line has three tracks from south of the Woodlawn station to the 138th Street–Grand Concourse station. The Woodlawn Line also has a connection to the Jerome Yard, where 4 trains are stored, just north of the Bedford Park Boulevard–Lehman College station.
