Abstract:

The Newark Light Rail (NLR) is a vital link in the region’s transportation network. This system introduced a new fleet of light rail vehicles (LRVs) and new stations in Belleville and Bloomfield in 2001. In 2006, new stations were opened in the downtown as part of a service connection between Newark Penn Station, the major transportation terminal in the state, and Broad Street Commuter Rail Station. The system connects with NJ Transit (NJT) bus and rail service as well as AMTRAK trains and Port Authority Trans-Hudson (PATH). The line is a subway–surface light rail line which originally opened in 1935 along the old Morris Canal right-of-way and was originally operated by the Public Service Corporation as its #7 line. NJT took over the line in 1980 and operated it from Penn Station to Franklin Avenue Station, a closed-loop system that was approximately 4 mi long. Since the 1950s single-unit Presidents Committee Car (PCC) cars, built in the 1940s, were running on the line until 2001, when NJT purchased 21 new articulated LRVs from Kinki Sharyo of Japan. The PCC cars have since been retired. In 2002, NJT extended the line approximately 1 mi (1.61 km) to Grove Street Station in Bloomfield, New Jersey, where a new yard and shop was built to service the new fleet of LRVs. In 2006, NJT opened the 1-mi-long (1.61-km) Broad Street Extension (BSE) from Penn Station to Broad Street Station in Newark. The system operates today with 21 LRVs over 9.9 route miles (15.9 km). The introduction of the LRVs and extensions to the system presented a variety of track work and vehicular engineering challenges in providing a renewal or refurbishment to a system that was built many years prior. The new LRVs were provided with a specific wheel back-to-back dimension and wheel profile similar to PCC cars in order to properly interface with the system specific track work that accommodated the PCC operation. This paper explains the challenges in the modernization of the system. Other transit authorities which may consider extending or rehabilitating their systems under similar conditions may benefit from the lessons learned. The following specific project elements, in support of the BSE Project and modernization–refurbishment of the system, are presented in this report: Penn Station Loop(s) rehabilitation; Fully guarded switches; Tunnel track direct fixation; BSE-embedded track on floating slab; BSE-embedded special track work; Tunnel trackside lubrication; and Onboard LRV lubricator for BSE-embedded track.
