In 1860 the Midland Railway was extended from Bedford into London and a station was built at Radlett connecting it with London. On 8 December 1865 the Ecclesiastical Parish of Radlett was created out of the eastern part of Aldenham and this marks the start of the modern history of the village. Development could only start when the landowners sold off their land for this purpose and this started in the final decade of the 19th century when land to the west of Watling Street was sold off. In 1910 the estate of Aldenham Lodge to the north of Shenley Hill was released for development and in 1935 the Newberries estate. Newberries mansion was demolished in the 1950s and Aldenham Lodge in 1964.
