A low resolution version of the Signalling Diagram for Earlswood Lakes Signal Box produced courtesy of the Signalling Record Society (S.R.S.). Details of how to purchase their full resolution content is available here. Earlswood Lakes Signal Box opened on 9th December 1907. The Signal Box was a standard Great Western Railway brick built design with a hipped roof and stovepipe chimney (type 7D). The operating floor was 29 feet long and 12 feet wide with the characteristic three up two down window panes. It housed thirty-one levers in a horizontal tappet, three bar locking frame. Earlswood Lakes Signal Box weekday opening hours for a selection of years are given:

Service Time Table Signal Box Opened Signal Box Closed
Summer 1916 Open continuously
Summer 1929 Open continuously
Winter 1930 Open continuously
Summer 1939 Open continuously
Winter 1945 Open continuously

The Signal Box here controlled the block sections on the main double line. The Signalman sent messages to the preceding Signal Box to give permission for trains to enter the block section on their line and used signals to indicate to train drivers when they were allowed to proceed. Distant Signals, distinguished by their forked tails and yellow colour (post September 1927) gave train drivers advance warning of the status of the next ‘Stop’ Signal. The Signal Box also controlled train movements associated with the station yard and sidings. The Signalman could set a route with the point switch levers.

These were interlocked with various types of signals (including ground signals and route indicators), operation of which informed the locomotive driver of the selected route and when to proceed. This interlocking with signals ensured that these indicated to other trains, when they could no longer proceed safely and had to stop. Visibility was important in the days before track circuits and the Signal Box was positioned where it could oversee the most complex trackwork.
