Signal Fact 50

The first illuminated signal box diagram was provided at Mill Hill Park on London's underground.

This showed the position of the trains on the diagram instead of using separate track circuit occupied repeaters.

Mersey Docks & Harbour Railway

This page should be regarded as “Work in Progress”. The webmaster will welcome additional information for this page.

In the list below the information is set out in tabular form, spread over four columns. The column entries are -

RailRef The Line Code used in RailRef system.
Line Detail The principal locations included within the Line Code. They are arranged in 'down' direction order. Locations shown are primarily stations and junctions to allow easy cross check against published atlases. Signal box names appear in italics where these are 'intermediate' to stations or have been shown to facilitate links from other pages on this web site. The inclusion of a station or junction name does not imply that there was always a signal box of that same name!
SBR The section reference used in the relevant Signal Box Register published by the Society.
ELR The corresponding Engineer's Line Reference(s). This will be blank for railways that never came within British Railways terms of reference. It will also be blank where British Railways had no surviving responsibility for infrastructure at the time the ELR system came into use.

The trunk route of the Dock lines ran for the most part beneath "The Docker's Umbrella", otherwise known as the Liverpool Overhead Railway. For that reason much of the route is 'invisible' on OS maps.
