167 St and Grand Concourse

167th Street (IND Concourse Line) once had a trolley station.

Construction and operation
The Concourse subway line was part of the Independent system. The street officially called Grand Boulevard and Concourse runs along the top of a ridge, and some of the more important crosstown streets burrow under the ridge. At several locations, the subway runs above the crosstown streets.

At 167 St, a trolley station was provided for the 167 St crosstown cars. At the entrances to the tunnel or underpass, the road is two lanes wide and had originally two trolley tracks in the pavement. At its midpoint, the tunnel widens, providing in each direction a trolley track, a trolley station platform, and a road lane. The trolleys could stop at the platforms while autos could run around to the right of the platform. Each of the two platforms had two stairs up, leading to the subway station and to the street. Starting at the lowest level, there were the trolley platforms; the subway station and mezzanines on each side; the subway mezzanine over the tracks; and street level of the Grand Concourse. Passengers could climb between the trolley station and the Grand Concourse street level outside the fare zone.

When the trolley line was abandoned in July 1948, the replacement Bx35 bus continued to use the platforms for many years, until about 1990, when it was moved to the street above for quicker transfers to other bus routes and the subway. The lower level was closed for pedestrians due to security reasons. Today the bus does not use the tunnel, and makes a stop at the corner of the Concourse, no doubt more convenient for transfer to the Concourse bus lines than all those stairs.

Trolley lines also crossed under the subway at Tremont Ave and Kingsbridge Road, but they did not have their own platforms.
