Cambrian Railway

Signal Fact 11

If the Ball can be seen, the line is right for the train to go in.

If the Ball is not visible, the train must not pass it.

Early Great Western Railway Instruction to Drivers.

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.

Published article: Railway Magazine, October 1898, including gradient profiles.
