UNDERSTANDING OPTIONS OF PASSENGER STATION HORIZONTAL CLEARANCES: GAUNTLET TRACKS, MOVABLE PLATFORM EDGES, AND DEDICATED STATION SIDINGS

摘要

One of the issues designers must resolve is the ability to maintain wide load clearances at passenger stations while still complying with level boarding requirements. This paper will discuss and evaluate different methods for providing the required clearances, including dedicated passenger train sidings, gauntlet tracks, and movable platform edges. As many Class 1 railroads do not typically allow installation, there is misconception that gauntlet tracks are no longer being used. Though under development, the AREMA manual does not currently address gauntlet tracks. This paper and presentation will discuss what gauntlet tracks are and the different possible configurations at station platforms. The paper will also highlight what are the benefits and drawbacks of these different options and where they are being used and by whom.
