Service Planning On Hudson–Bergen Light Rail: The Systems Engineering Basis

Networked rail transit systems present scheduling and operational issues which are significantly more challenging than railways which are comprised of a series of individual, point to point lines. The recent trend in North American light rail transit (LRT) is for systems which were conceived and constructed to relatively simple configurations to evolve into relatively complex networks. These networks include trunk lines with multiple branches, complex junctions, and full or partial loop operations. An accompanying trend is the inclusion of full train control systems incorporating automatic train protection–advanced train control on light rail and the use of complex track and interlocking configurations. For such systems, scheduling for reliable high density operations requires a priori analysis of the capabilities of the engineering systems; this analysis must include such items as interlocking configurations and the headway design of the train control system. This paper provides a case study describing the methods utilized for service scheduling on the Hudson–Bergen Light Rail, which is a high technology, high service density light rail system having a moderately complex network configuration. Schedule making is a complex exercise which includes evaluation of cycle times, equipment utilization and run cuts. This paper does not discuss schedule making, rather it describes the systems engineering analysis which is a separate and distinct exercise from schedule making, and which must, in fact, serve as a prerequisite to schedule making.
