Changes

Construction of the first two signal boxes at Bewdley was authorised by the GWR Board in October 1877 as part of the opening of the Kidderminster Loop line. They were the first 'proper' signal boxes on the Severn Valley Railway, all other boxes dating from after 1880<ref>[[Bibliography | Marshall (1989), p128]]</ref>. There is uncertainty as to whether Bewdley North and Bewdley South are these original 1877/78 build boxes or later (19th century) replacements. The lever frame in the Box dates from 1909 and has an early example of standard GWR three-bar vertical tappet interlocking. The interlocking has had minor alterations in preservation to suit preservation needs, but much is as it was prior to 1970.
