Sudbury signal box photographed on 30 June 2020. A North Staffordshire Railway (NSR) type 1 structure dating from 1885 the box is fitted with a McK&H 1873 patent 5" 25-lever frame. There's more than a hint of McKenzie & Holland (McK&H) design here though and the box closely resembles Great Northern Railway (GNR) structures of the same period.
