This document presents the maintenance and improvement principles of substructure and track bed layers for existing railway lines.

It provides comprehensive technical expertise and managerial knowledge with precise explanations for use.

The first chapters are devoted to showing the general cross-sections of conventional ballast tracks and continues by listing the requirements of a railway track and describing the potential problems that can occur in existing lines, related to cuttings, natural slopes, embankments, platforms, track bed layers, slabs, and drainage and catchment systems.

Taking the previous ideas into account, a methodology for performing inspections is proposed based on different steps: basic and detailed in-situ inspections and ground investigation in zones with problems. Once the inspections are done, a comprehensive list of solutions for the corrective work is provided.

Finally, the usual procedures for maintenance, renewal, risk mitigation and improvement work are described.
