The first motor car had arrived in 1899 and buses started running on the island in the 1920s, and by the 1930s, competition from motor buses had rendered the railways unprofitable, with final closure coming in 1935 after a fire disaster (except for the later German reintroduction of rail during the military occupation). Jersey Airport was opened in 1937 to replace the use of the beach of Saint Aubin's bay as an airstrip at low tide, and the railways could not cope with the competition.
