Currently, more than 500 signal boxes across the UK are in the process of being made redundant as the modernisation of Britain's railway continues. The surviving Victorian boxes, some of which have been part of the railway for around 150 years, will be retired as new technology is introduced. Since the announcement two years ago, 26 Signal boxes across England have earned listed status to preserve the country's rail heritage, but the vast majority will either be removed or allowed to continue to fall into disrepair.
