In 1919, Reading Corporation started operating its first motor buses. These ran from Caversham Heights to Tilehurst, running over the tram lines and beyond the tram termini. Because of the state of the track, the Bath Road tram route was abandoned in 1930, followed by the Erleigh Road route in 1932. Eventually it was decided that the tramways should be abandoned and replaced by trolleybuses, operating over extended routes. The last tram ran on the Caversham Road to Whitley route in July 1936, and the last car on the "main line" ran in May 1939.
