The primary station building is located on South Clinton Avenue on the west side of the tracks, with a smaller building on the east side. The four-track below-grade Northeast Corridor widens to eight tracks at the station: four platform tracks serving two accessible island platforms, two center bypass tracks, and two outside siding tracks. A non-accessible side platform, not normally in use, is located next to the eastern siding track. A footbridge connects the station buildings and the platforms. The terminal for the River Line, with two tracks and two side platforms, is located across south Clinton Avenue from the main station building.
As with many PRR stations, especially in New Jersey, the station became a Penn Central station once the New York Central merged with the PRR in 1968. Amtrak took over intercity railroad service in 1971, but Penn Central continued to serve commuters, even as the station building closed in 1972. In 1976, the bankrupt Penn Central and Amtrak built the new Trenton Rail Station just before Penn Central's rail assets were taken over by Conrail. It was built to a standard template used at many Amtrak stations built in the 1970s and early 1980s, with a rectangular shape and a boxy, cantilevered metal roof. NJ Transit Rail Operations took over the station when it acquired Conrail's New Jersey commuter lines in 1983, but the station continued to serve Amtrak as well as SEPTA Regional Rail to Philadelphia. From 2006 to 2008, a major reconstruction project authorized by NJT took place with $46 million worth of federal aid, and $33 million worth of state funding that resulted in the current Trenton Transit Center.[6]
