Washwood Heath Sidings No 1 Signal Box seen on 25th October
1964 was one of three boxes controlling traffic leaving Birmingham. See image
'mrwhg1014' for a schematic layout of the western
side of Washwood Heath Sidings. According to
The Signal Box, 'the
Midland Railway pursued its own ideas right from the very start of signalling,
and the Tumbler locking frame (introduced around 1870) was their first design
to be built in large numbers. In a complete departure from other manufacturer's
practice, the entire locking frame was built above operating floor level, with
the lever catches and interlocking mechanism all encased in a black metal
surrounding. This feature had several benefits, apart from cleanliness, in that
it allowed maintenance to be carried out in good light and also permitted low
or ground level cabins to be built without complication. A side benefit, given
that the lever pivoted above signalman's foot level, was that the levers were
easy to get a powerful swing on. This style was perpetuated right through to
the British Railways era on the London Midland Region.'
