The former Romanesque station building, near the north end of the inbound (to Grand Central Terminal) platform, was constructed in 1888, making it the second oldest surviving station building on the New Haven Line, according to a plaque inside the building. It was also a replacement for the original Mamaroneck New York and New Haven Railroad station built in 1848 across Mamaroneck Avenue on the corner of Mount Pleasant and Bishop Avenues. The original station at Mamaroneck burned in February 1889.
