PRS-Neoloy® Tough-Cells optimize the performance of both railways track and rolling stock and maximizes the economic worthiness of new track construction and track rehabilitation. Safe and efficient operations of railways seek to minimize degradation of mainline track surface geometry and ballast layers; this is critical on track with high speed passenger operations and/or heavy freight loads. This section describes how Neoloy® based cellular confinement system (Tough-Cells) reinforces track substructure and stabilizes the ballast layers, subgrade and embankments to minimize track degradation and maintenance cycles.
