See detailed information for ELR NBS1 and Interactive Map.
⚠️ Horizontal curvature shown below is based on the digitised notional ELR centre-line, reported at 110 yard intervals. The average radius computation is weighted, however this should be treated as indicative only. The computed minimum and maximum radii are shown for completeness, and often report a much tighter radius than the physical railway. Radii calculations are influenced by the digitisation quality, and often produce inaccurate values at the extremities of the ELR, areas of tracks divergence, and locations of very tight curvature.
