Go West Midlands was a bus company in the West Midlands. It was a subsidiary of the Go-Ahead Group in March 2006.
On 2 December 2005, the Go-Ahead Group purchased Diamond Bus and in February 2006 Probus Management (trading as People's Express) with over 100 vehicles and merged the two companies to form Go West Midlands.
In 2006, Diamond relaunched its image, by increasing its frequency on route 16, which basically matched that of Travel West Midlands and increased its frequencies on routes 17, 63, 64, 74 and 87.
However, in November 2007, Diamond withdrew its services on routes 17 and 63 and majorly altered its operations on routes 74 and 87 (cutting parts of the route off completely).
Diamond also lost many Centro and Staffordshire County Council contracts to other operators.
In March 2008, Go West Midlands was sold to Rotala and rebranded as Diamond Bus.
As at March 2007, Go West Midlands operated a fleet of over 130 buses.
