Unseen by many Londoners, the network of night buses that begins work as the daytime routes wind down their operations has reached a record size in recent years as London's night life has expanded. This book, the fruit of over 12 years of research, records the development of the services from their beginning in 1913 up to the eve of the largescale expansion that took place from 1984. Night tram services, dating back to 1899, and trolleybuses are also covered. Photographic coverage of the night buses was limited in the days before high speed photographic film, but Philip Wallis has gathered an excellent selection to illustrate his definitive text.
