Full House At Harlem. An elevated view of the MTA Metro-North Railroad Harlem-125 Street Street Station on the afternoon of August 30, 2018 shows a wide cross section of the roster. A pair of M7A trains is seen on the tracks on the west side of the station, while a coach train and an M8 occupy the east tracks. The current 1897 station was built by the New York Central and Hudson River Railroad, the descendent of the 1844 ground level station at this location. All of the Metro-North trains en route to Grand Central Terminal pass through this location, which creates a lot of interesting meets.
