Close up of image 'lnwrberk525' showing the approach to
Berkswell and the duplicated tall signals needed because of the bridge being
sited on the curve. As can can also be seen the post to the tall signal nearest
the down line has a signal arm attached some 12' above ground level. This arm
is a "repeater" of the one at the top of the post so that crews could easily
see it if they had stopped at the station. It is easy to forget that in the
days of steam prior to the "Clean Air Act" thick fogs were common through the
winter and were so bad giving severe visibility problems that the top signal
would not be seen from ground level. On such occasions "fog men" would be
required to stay at signals and to place percussion caps on the rails to
provide drivers with an understanding of whether the signal they were passing
was at danger, caution or clear. This being achieved by the number of caps
placed, one being clear, two being caution and three for danger.
