The H37 was initially created in the 1980s when the 37 was split up in three segments, the 37 between Putney and and Peckham, the 337 between Richmond and Wandsworth and the H37 between Hounslow and Richmond. Originally the H37 operated using Dennis Dart DTs. In the late 90s low flow Darts were introduced and used until 2010 when Optare Tempos were introduced. Because of overcrowding on this route during school periods, there is a campaign currently to either use double deck vehicles on the H37 or create a school journey route. [1]
