Additional information is always gratefully received, whether entirely new records (particularly historical records), or information to fill in gaps or correct errors, via the contact link under the Miscellaneous entry in the navigation bar above.  Thank you.

Introduction | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z | Lines without codes | ELR/LOR converter | LUL system | DLR system | Canals

This listing gives the British Waterways/Canal & River Trust equivalent to the ELR system.  Information is derived from records quoting codes in use and there are thus some gaps for which "translations" are unknown (the codes themselves are known).  There are also canals for which the code is not known.  In both cases, further information would be welcome.
