View of the larger replacement standard type 28b signal box
constructed at Bentley Heath Crossing as part of the quadrupling of Birmingham
Main line between Olton and Lapworth, which was completed in May 1933. The new
signal box was opened in 1932 on the same side of the track as the old signal
box, but on the opposite side of the level crossing (seen on the right of the
photograph). This type 28b signal box design had been introduced at the turn of
the century and over a hundred were constructed by the Great Western Railway,
however only a few were built after 1924 (although being of an all timber
construction several were relocated). The design had several distinctive
features; including horizontal boarding, three up and two down sliding windows,
a gabled roof with no finals and a plain gabled end. The signal box at Bentley
Heath was 33 foot 2 inches long by 12 foot 2 inches wide and had three torpedo
vents in the roof ridge. The internal layout was typical of most signal boxes
with the lower floor housing the locking frame, while upper operating floor
contained the frames levers and signalling equipment. At Bentley Heath
there was a vertical tappet, three bar locking frame with 49 levers at 4 inch
centres.
Eleven of the levers were spare at the time of
construction. At the right hand end of the signal box nearest the level
crossing was a wheel which controlled the level crossing gates. Two levers
(No.1 & 2) locked the gates in their open and shut positions, while a
separate small two lever frame locked the pedestrian wicket gates. Four levers
(No.7, 15, 35 and 44) allowed warning detonators to be automatically placed on
each of the four running lines. Other levers operated the block signals and
those associated with the fast crossover between main and relief lines, where
additional locking was required on the two facing switches. The up and down
refuge loops had also been reinstated between Knowle station and the level
crossing at Bentley Heath, so levers were necessary to control the signalling
and switches associated with these. A ground frame was provided for the
Ministry of Foods Cold Store Siding, when this was installed on 16th May
1943 and this was locked with an Annetts key released by lever No.14 in
the signal box. An open steel lattice footbridge was constructed over the four
lines adjacent to the signal box as part of the widening works in 1933 to allow
pedestrians to cross the line when the level crossing gates were shut.
