The Princeton Branch is a commuter rail line and service owned and operated by New Jersey Transit in the U.S. state of New Jersey. The line is a short branch of the Northeast Corridor Line, running from Princeton Junction northwest to Princeton with no intermediate stops. Also known as the Dinky Line, or Princeton Junction and Back, the branch is served by special shuttle trains. (Dinky is a term for a small locomotive. The term is on face anachronistic, because the line is today served by a single Budd Company Arrow III electric coach car, although the Federal Railroad Administration considers any power car to be a locomotive.) NJ Transit has also considered using diesel multiple unit coaches on the line. The Princeton Branch provides rail service directly to the Princeton University camp
