<p>In the first three decades of the twentieth century, single-track laterally positioned trolley infrastructure was responsible for most of the interurban and suburban transit traffic in the northeast United States. These designs are nowhere to be found in today’s light rail landscape in the United States, but they can be found in Europe. With the changing nature of suburbs in the Northeastern United States, where public rights-of-way are limited, light rail lines built to this design might again make sense. A feasibility study was conducted to determine if single tracking and/or lateral positioning of light rail lines are design choices that are practical under modern conditions. This article presents the outcomes of an expert panel discussion and modeling to determine that feasibility. This article also concludes with guidance on design implementation factors such as right-of-way width and design, safety devices and considerations, side roads and driveways, and applicable light rail service headways.</p>
