Permanent Way - Dimensional Diagrams

For more information on tracks, also see the permanent way FAQ page.

Shown below are diagrams (not to scale) of typical track layouts on embankments and in cuttings. Dimensions shown are for both BG (1676mm) and MG (1000mm), except for the centre-to-centre distances for double lines and the track formation widths which are shown for BG and MG (the latter marked with 'MG' in parentheses). These are adapted from diagrams published by IR. Also see the page on a detailed diagram of a track formation.
