The Wiki pages listed below describe bus routes operating within the metropolitan borough of Solihull in the West Midlands (with the majority also operating, to a greater or lesser extent, within Solihull's larger neighbour Birmingham) with a particular emphasis on their 'recent' history (last 50 years).
The 3 December 1973 was a significant date for Solihull's buses. Bus services in Solihull were originally provided by the Midland Red bus company but from this date all services operating within the new West Midland County were taken over by the recently formed West Midlands Passenger Transport Executive (itself formed from, most significantly, Birmingham City Transport). Instead of the long held agreement that Birmingham buses would not operate beyond the city boundary whilst Midland Red's generally less frequent services would charge fares above that levied on the Corporation buses to discourage 'local' passengers, in the years that followed route and fare integration occurred with, in some cases, many further changes also occurring since deregulation and the formation of West Midlands Travel (now operating as National Express West Midlands) in 1986.
National Express West Midlands (West Midlands Travel Ltd) remains the major operator in the borough and whilst they are the direct descendants of WMPTE and hence BCT (just look at the name engraved above the entrance to NXWM's Yardley Wood garage), we have in some ways come full circle since 1973 as not only were WMT Ltd's parent company originally formed out of the National Bus Company subsidiaries coach routes which included Midland Red's longer distance routes, but now NXWM's recent crimson livery means, 50 years on, we can once again still see scarlet coloured buses operating in Solihull.
For the early history of the buses of East & Southeast Birmingham the book 'Birmingham Buses Route by Route 1925-1975' by Malcolm Keeley is recommended. There is also some relevant information contained within the article 'A transport history of Yardley' by P L Hardy, including the fact that Midland Red services along the Stratford, Warwick and Coventry Roads commenced in 1914. Additionally, the Services section of the MidlandRed.net website may in time include further detail on the early history of Midland Red routes in the area (example). The 1973 transfer of services described above most significantly affected the boroughs of Solihull and Dudley. The article reproduced here lists all of the services involved, with further information about the transfer here.
