By 1912 the Birmingham Corporation Tramways had used its statutory powers to acquire the city's tramways which it did not already own, and wanted to consolidate the operation of bus and tram operations in the city. Since it was going to be difficult for BMMO to expand in the city, it reached agreement with the corporation to operate services from outside Birmingham into the city and transfer its services within the city to the corporation. The company then expanded outside Birmingham, and moved its headquarters to Bearwood in Smethwick.
