Reading Buses will recreate the Inauguration of Motor Service, which was the original bus route in the town, on Friday 6 December.
A modern example of its fleet will run between Caversham Heights and Tilehurst. It will then return to the Town Hall for a short presentation.
Aboard will be various Reading Borough Council members and officers. Joining them will be members of the Reading Buses leadership team, retirees, long-serving members of staff and some new recruits. The bus will follow as closely as possible the original route of a century ago.
The same route will be re-enacted by historic buses that are open to the public on Sunday 8 December.
