Birdingbury Station: lnwrbird3972
A late 19th century view of Birdingbury station showing LNWR
slotted semaphore signals on the right adjacent to the goods yard. The signals
are 'lower quadrant' meaning that danger is indicated by a horizontal position
(9 º'Clock position) whereas 'Clear' or safe, is indicated by the arm
being lowered to a 7 º'Clock position, as seen above. In later years most,
but not all - GWR being an example - railway companies installed upper quadrant
signals where the semaphore arm moved from the horizontal position, which was
still indicating' danger', upwards to a position equivalent to 11 º'Clock
on a clock face.
