"London Bridge Is Falling Down" (also known as "My Fair Lady" or "London Bridge") is a traditional English nursery rhyme and singing game, which is found in different versions all over the world.

The Battersea Park rail crash occurred on 2 April 1937, just south of Battersea Park railway station on the Southern Railway, in London.
 Two electrically driven passenger trains collided on the Up Local line; the second train, from Coulsdon North to Victoria, had been allowed into the section while it was still occupied by the first train, from London Bridge to Victoria.
 The signalman at Battersea Park, G. F. Childs, believing there was a fault with the Sykes electromechanical interlocking apparatus which was installed at the box, had opened up the case of the instrument and inadvertently cleared the interlock which should have prevented this situation.
 The official enquiry ruled that he subsequently accepted the Coulsdon train, although he should have been aware that the London Bridge train had not cleared the section.
 Ten people were killed, including the guard of the London Bridge train, and eighty people were injured, seven sustaining serious injuries.
