Tremont station is a commuter rail stop on the Metro-North Railroad's Harlem Line, serving the Tremont section of the Bronx, New York City. The station is in an open cut at the intersection of Park Avenue and East Tremont Avenue. Service at Tremont is limited; trains stop every 30 minutes during rush hours, every hour otherwise. The station has two high-level side platforms, each two cars long, serving the outer tracks of the four-track line.

The Harlem Line is an 82-mile (132 km) commuter rail line owned and operated by the Metro-North Railroad in the U.S. state of New York. It runs north from New York City to Wassaic, in eastern Dutchess County. The lower 53 miles (85 km) from Grand Central Terminal to Southeast, in Putnam County, is electrified with a third rail and has at least two tracks. The section north of Southeast is a non-electrified single-track line served by diesel locomotives. Before the renaming of the line in 1983, it eventually became the Harlem Division of the New York Central Railroad. The diesel trains usually run as a shuttle on the northern end of the line, except for rush-hour express trains in the peak direction.
