An Engineer's Line Reference (ELR) is a three alpha, or four alpha-numeric, code used to uniquely identify a railway line on the main-line railway of Britain owned, or maintained, by Network Rail but official railway records retain the ELR codes for lifted branch lines and any structures such as bridge abutments, tunnels, viaducts, retaining walls etc.…
