So many posts in the last two days that this looks a while ago. I hesitate to contradict Lloyd on bus matters but I can say that Midland Red regularly operated on the B82 route at weekends, probably with just the one vehicle. As Lloyd will know in those days there were nearly always three BCT buses at the B82 stop in Bearwood Bus Station and regularly I would see a Midland Red among them at the weekends. I knew someone who worked in the offices at Bearwood and he would do overtime at weekends as a conductor and his regular job was on the B82. He told me how busy this route was as he would still be loading at the first stop on Bearwood Road oposite the Midland Red Garage when the next BCT bus would be turning out of Adkins Lane from the bus station. He was always greatful if his driver would slow down on Waterloo Road to let the B86/B87 go past at the Cape Hill junction.
Conversely when i worked in Smethwick in the 1960s I would often see at lunchtime a BCT bus, a rare sight on Smethwick High Street, on a B85 shortworking to St Pauls Road Smethwick.
