[16] Shortly after the purchase, the CMS Carlislebus operation began employing AEC Routemasters acquired second-hand on competitive bus corridors in and around Carlisle.

[2] Between 1987 and 1989, Cumberland purchased many of its previous competitors based across the county, taking on operators such as Yeowart's, Kirkpatricks of Bingham, the bus services of Brownriggs of Egremont.

[21] In July 1990, Cumberland launched a Lake District open-top bus service, running every 20 minutes between Ambleside, Windermere and Bowness-on-Windermere using a fleet of four Bristol VRs acquired from Stagecoach Southdown.

[22] Cumberland began experiencing financial difficulties during the early 1990s, resulting in wages being cut, older Leyland Nationals being replaced by Alexander bodied Mercedes-Benz 811D minibuses, and the last of the Carlislebus Routemasters being withdrawn by the end of 1992.

[24] As of the July 1987 purchase by Stagecoach Holdings, Cumberland Motor Services operated a fleet of 230 buses based at seven depots in north and west Cumbria.

[25] Under Stagecoach ownership, Cumberland took delivery of two of the three 96-seat Alexander bodied Leyland Olympian tri-axle 'Megadekka' buses ordered by the group in 1990, which were used primarily on school services.
