Shand, who had also overseen construction of the now-demolished Philadelphia Broad Street Station. The historic 1918 station was constructed when the branch was part of the Pennsylvania Railroad (PRR) under the direction of architect-engineer Alexander C.

The original 1865 location of Princeton station, in what became the university's Blair Courtyard, 0.15 mi (0.24 km) south of Nassau Street, was replaced by the 1918 station, built on a site 0.25 mi (0.40 km) further south. The new permanent Princeton station, designed by architect Rick Joy, opened on November 17, 2014, with construction continuing on a complex of arts and dining buildings in the surrounding area.

Approximately 1,200 ft (370 m) to the southeast, a temporary station operated from Augthrough November 9, 2014, accompanied by various bus routes shuttling among the old station, the temporary station, and Princeton Junction. The historic 1918 train station closed permanently on August 23, 2013. Plans to relocate Princeton station 460 ft (140 m) south, proposed by the university in 2006 and approved by NJT and the Princeton Regional Planning Board, were met with opposition from some commuters, residents, alumni, and transportation advocates. Service on the Princeton Branch was suspended from Octothrough May 11, 2019, replaced by shuttle buses, as part of NJT's systemwide service reductions during the installation and testing of positive train control. Initial studies have been conducted to add a bus transitway along the Dinky right-of-way as part of a proposed bus rapid transit system. Now running 2.7 mi (4.3 km) along a single track, it is the shortest scheduled commuter rail line in the United States. The shuttle train between the two stations is known as the 'Dinky', and has also been known as the 'PJ&B', for 'Princeton Junction and Back'. At the branch's southern end at Princeton Junction, connections are available to NJT's Northeast Corridor Line and peak-hour Amtrak trains. Princeton is the northern terminus of the Princeton Branch commuter rail service operated by NJ Transit (NJT), and is located on the Princeton University campus in Princeton, New Jersey.
