On Friday 1st June 1928, Birmingham and Midland Motor Omnibus Company Limited (BMMO—Midland “Red†Motor Services) started operation of a network of local area bus services in Worcester City as part of the “Worcester Agreementâ€, replacing the electric tramway network that ceased operation on the previous day. The new Worcester bus network was the first local area network introduced by BMMO to carry local area prefixes, having route numbers with ‘W’-prefix.
Service W10 was introduced at the formation of the network running between Worcester City Centre (The Cross) and Bath Road, terminating at Norton Turn. Buses ran once an hour in each direction throughout the day, seven days a week. Service W7 also ran over the same route but as far as the Berwick Arms. These ran with a higher frequency of three buses and hour Monday to Saturday or two buses an hour on Sundays.
By the 1950s, Service W7 has been withdrawn and replaced by additional Service W10 journeys that ran from the High Street with a frequency of every 10-minutes throughout the week, but the frequency had been reduced to run every 15-minutes on Sundays by the late-1960s.
In the late 1960s or early 1970s, Service W10 was withdrawn. As a replacement, certain journeys of Service W9 running between Worcester City Centre and Warndon via Tolladine Road were extended past Warndon to return to Worcester City Centre (High Street) via Bilford Road, and continue to Bath Road. This new route ran as Service W39. At the same time, Service W2 running between Worcester City Centre and Ombersley Road was also extended to Bath Road.
