In southeastern Pennsylvania, CSX Transportation sought to increase the productivity of its Trenton Line freight rail service by improving the vertical clearance of its tracks so it could operate double-stack container cars along the busy corridor. Investigations using technologies ranging from aerial and laser surveys to lidar, GPS equipment, ground-penetrating radar, and seismic refraction techniques helped determine the geotechnical conditions along the route and inform the resulting design. A combination of foundation support structures, protection slabs, and soldier-pile walls was used to protect the surrounding structures and utilities during the track-lowering process, which included both traditional and innovative excavation methods.
