On the evening of 4 December 1957, two trains crashed in dense fog on the South Eastern Main Line near Lewisham in south-east London, causing the deaths of 90 people and injuring 173. An electric train to Hayes had stopped at a signal under the bridge, and the following steam train to Ramsgate crashed into it, destroying a carriage and causing the bridge to collapse onto the steam train. The bridge had to be completely removed; it was over a week before the lines under the bridge were reopened, and another month before the bridge was rebuilt and traffic allowed over it.
