Operation of W. & B. Woodyatt's service between Barnards Green, Great Malvern, North Malvern and West Malvern passed to the Birmingham and Midland Motor Omnibus Company Limited (BMMO—Midland “Red” Motor Services) on Saturday 22nd April 1916, as Service 48. All journeys were operated using a one Tilling-Stevens petrol-electric omnibus housed at Worcester (St John's) depot.
Although BMMO did not loose any of their vehicles to the war effort, fuel was in short supply and vehicles were being run on a mixture of paraffin and petrol which was less than ideal and vehicles struggled on the steep hills around Malvern. On Thursday 1st March 1917, fuel rations were again reduced and the Ministry of Munitions ordered operators to abandon all services that were not of national importance, so less than one year after being introduced Service 48 was withdrawn. Service 25 was cut back to run only between Worcester and Malvern Wells at the same time.
In a meeting with local authorities held on Monday 1st July 1918, the BMMO Traffic Manager, Mr O.C. Power, agreed to reinstate Service 48 between Great Malvern and West Malvern on condition that safety improvements were made to West Malvern Road at Redan Corner,†and that a suitable bus turning point at West Malvern was provided. The Barnards Green to Great Malvern section of the route was not to be reinstated at this time because the Tilling-Stevens petrol-electric omnibuses used by BMMO struggled to cope with the steep hill at the top of Church Street.
A new turning point was created on West Malvern Road at The Dingle, a site to the south of West Mavern near the junction of Maton Road (now named Harcourt Road), by clearing and resurfacing a disused quarry at the cost of £25 (about £1,000 adjusted for inflation). Later (c. mid-1930s) a brick-built shelter was erected and the site continued to function as a terminus and bus turning point until the withdrawal of Service M16 in October 1976. On Monday 3rd March 1919, changes were made to the other end of the route when the terminus was moved to a former taxi rank outside Rose Bank Public Gardens, and this site continues to serve as the starting point for West Malvern bus services to this day (now provided by First Midland Red Service 675). At the West Malvern end of the route, certain journeys were extended from c. May 1919 to continue to Wyche Cutting, before returning via West Malvern to Great Malvern. The direct route between Wyche Cutting and Great Malvern was not used as it was considered too dangerous for omnibuses at the time.
Over the following years, BMMO expanded their local omnibus network in the Malvern area with a number of new routes, all of which ran as Service 48. The first new route was introduced in June 1919, running between Great Malvern and Malvern Link to provided much needed additional capacity and avoid overloading on Service 25. From September 1919, an additional route was added from Great Malvern to Barnards Green and Poolbrook, operating five return journeys each day, finally replacing the service that had been withdrawn due to fuel rationing over two years before.
BMMO and other operators such as W. & B. Woodyatt ran a number of Summer Season tours from Malvern, starting in 1919, and additional omnibus route to locations outside of Malvern were established, such as BMMO's Service 50 to Tewkesbury from July 1921. However, for the next few years there was very little change to local Malvern Service 48, except for a direct route to Wyche Cutting. This was introduced on Saturday 15th July 1922, and during the Summer Season it was extended along Jubilee Drive to British Camp. From about the same time, the Wyche Cutting extension to the West Malvern route was changed to return to Great Malvern directly via Wyche Road, and became known as the “Round the Hills†route.
The most significant changes to Service 48 came on Saturday 17th May 1924, when two new routes were introduced. The first of these was between Great Malvern Post Office and the junction of Peachfield Road and St Andrew's Road, which BMMO called “Golf Linksâ€. The second new route was between the Unicorn Inn in Great Malvern and the junction of Belmont Road and Somers Park Avenue, with certain journeys continuing to Malvern Link.
From Saturday 16th May 1925, BMMO renumber their entire network with new route numbers based on geographical area. Local Malvern area routes, previous all known as Service 48, were renumbered into the range 270–279.
†Redan Corner is the local name given for the tight bend on West Malvern Road (B4232), situated at the northern most edge of the Malvern Hills. The name was taken from a huge, barrack-like building dating from the 1850s that latterly became The Redan Public House. The building was a well known local landmark, being built on the side of a very steep hill near the bend, but after standing derelict for many years it was demolished in June 1980.
1 Certain journeys continue to Wyche Cutting from c. May 1919.
2 Certain journeys continue to Great Malvern via Wyche Road from July 1922 as “Round the Hills” route.
3 Certain journeys continue to British Camp during the Summer Season only.
4 Certain journeys continue to Malvern Link.
