Woking Electrical Control Room (2016)

Built in 1936 by Swedish firm Asean, the Woking Electrical Control Room was one of five control rooms managing electricity for the Southern Rail network, featuring an oval white-domed interior with decorative cast iron poles and control panels for various substations. The facility operated with just two engineers until 1997 when its functions were transferred to a new substation, and it now survives as a Grade II listed building that opens occasionally for heritage visits. Of the original five control rooms, only one other survives, though it has been stripped and repurposed for storage.
