Covers Engineering Code provisions on classification of surveys and their terms of reference, principles governing railway alignment, ruling gradients and grade compensation for curves, hill surveys, catch sidings, and tunnels. Also covers the preparation of survey reports for RECT, PECT, and FLS stages, and project estimates.
Key Terms
- Ruling gradient — the steepest gradient permitted on a section without additional traction assistance; curves require grade compensation.
- RECT, PECT, and FLS are successive survey report stages before a new line project is finalized.
