At the branch's southern end at Princeton Junction, connections are available to NJT's Northeast Corridor Line and peak-hour Amtrak trains.

[13][14] 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.

[26][a] In 2006, Princeton University announced its intention to construct a new arts center, calling for the replacement of the 1918 station house, the shortening of the trackage right-of-way, and the creation of a new terminus 460 ft (140 m) to the south.

[27][28][29][30] Rail advocates opposed the relocation, fearing that access to the new station would be less convenient, resulting in decreased ridership that could "threaten the train's existence.

[34] Meanwhile, the borough, township, and university prepared a memo of understanding in which the school promised to fund a transit study and provide other benefits in exchange for rezoning for the combined arts/transit project.

Parts of the proposals call for the construction of a "Dinky Transitway" along the Princeton Branch right-of-way, which would incorporate the rail service and add exclusive bus lanes and a greenway for bicycle and pedestrian traffic.

[10] In April 2012, the university submitted a revised plan for the arts and transit center, calling for the extension of the station's freight house onto the right-of-way for possible use as a restaurant.

The Regional Planning Board introduced an ordinance requiring the land be preserved for a transportation right-of-way that could eventually extend farther into the central business district at Nassau Street.
