Walsall trolleybuses - Stafford Street : 863 (TDH913)
In 1967 a new one-way traffic system was introduced in the centre of Walsall.
Part of this scheme was that part of Stafford Street was to be a one-way street. However trolleybuses were allowed to remain travelling in the "wrong direction" having a trolleybus lane for this purpose per this video taken around 1968.
