context_page_description: Alder Valley was a bus operator in South East England.
context_section_description: Alder Valley was formed when National Bus Company (NBC) subsidiaries Aldershot & District Traction (A&D) and Thames Valley Traction (TV) merged on 1 January 1972.
  The name Alder Valley was an amalgamation of the former names, but not representing any geographical feature or area. Despite the merger, the company initially maintained two divisions, Reading (covering the former TV area) and Aldershot covering A&D's area, each of which continued to issue its own timetable booklet. From 1 November 1973 these divisions were renamed North and South. Thames Valley had also managed the South Midland express services between Oxford and London, but these were transferred to City of Oxford Motor Services in 1971. The new company's head office was at the former TV headquarters in Reading, but the Aldershot office was retained as a divisional headquarters, and in 1981 became the head office, allowing the Reading site to be sold for redevelopment.
