Route 81 bus running day

Route 81 was one of the first fruits of the takeover of the London General Omnibus Company (LGOC) by the Underground Group in 1912, connecting the then western end of the District Line at Hounslow with Slough and Windsor. The route no longer served Windsor after 1963, but still today runs between Hounslow and Slough – 110 years of service to London.

Our free bus service, which operates in addition to the TfL service, will feature a range of bus types which have operated the 81 over the years (and a few that haven’t!). More modern preserved buses that do not comply with the London LEZ will operate between Colnbrook and Windsor only. Several related routes will also be operated, as follows; for more details, see the Route 81 history.
