Sorry Tramp but Midland Red no longer exists In Brum as far as I know..
The main bus company in the Midlands, and a lot of other parts of the country are now run by Nation Express. This firm is massive, I understand they have Bus routes in Australia, Europe and god knows where else.
They were until recently known as Travel West Midlands around here.
They also run the Coach Network around the country.I don't reckon much to the management, I have complained to them before now and have actually been told that they are not a Bus Service They are a Bus Company there to make a profit.
You will find their website easy enough.
Digbeth Coach station is by the way undergoing a major Facelift/Rebuild
I don' know Worcester very well so don't know of any Mid Red services around there.
