Engineer's Line Reference

Browse, map, and cross-reference every ELR across the Network Rail infrastructure — by code, location, or administrative area.

List • Hexmap • Minimaps • Nearest Places • Council Administrative Areas

Explore the entire GB network at a glance with the Hexmap — a national view where each hexagon is colour-coded by ELR density. Click any hexagon to reveal the ELRs it contains and view localised Minimaps.

Line of Route

Lines of Route group related ELRs into named operational routes, available as regional tables and a national overview map. The National Map displays Network Rail regions colour-coded; clicking any region expands the LORs within it.
