Close up of image 'lnwrbhm_sa2320' showing the headshunt used
when marshalling freight for Curzon Street Goods depot and Landor Street
running adjacent to the embankment. Landor Street commenced at this point, off
Lawley Street, and was an incredibly long straight section of road to find in a
city centre see image 'mrbhm_sa1902' which shows
the road continuing past the former Midland Railway's Camp Hill line and on to
Adderley Park where it became Arden Road. The track on the left is the head
shunt which allowed trains to be made up (marshalled) for Curzon Street Goods
Station as its sidings were seriously limited in accommodating full length
trains. The white disc beneath the signal repeated the signal seen above. These
disc signals were devised at about the time of the First World War a new design
appeared, consisting of a more or less circular plate perhaps a foot in
diameter, usually painted white with a red stripe across the middle. The disc
was pivoted in the centre so it could rotate, on early examples the disc was
bolted to the arm of the miniature semaphore signal. When the red stripe was
horizontal it meant stop, when at forty-five degrees it meant all-clear, for
night operation small holes with coloured glass lenses were fitted to the plate
and an oil lamp mounted behind to give a clear indication. These rotating disk
signals could be either upper quadrant or lower quadrant depending upon the
preference of the owning company. Ground signals were only used for shunting
purposes and by convention are mounted to the left of the track (as is the case
for every signal). Information on the disc signal courtesy of Mike
Smith.
