Ce rapport d\u00e9crit l\u2019utilisation de la technologie LCMS pour l\u2019inspection automatis\u00e9e de la ligne Harrisburg d\u2019Amtrak. Dans le cadre de ce projet, un v\u00e9hicule d\u2019inspection pour essais sur rails a \u00e9t\u00e9 \u00e9quip\u00e9 de capteurs LCMS-2 pour collecter des scan 3D des surfaces des rails, des traverses, des ballasts, des attaches, des joints et des barres de jonction.
