While TrawsCambria was co-ordinated by the Welsh Assembly Government, the actual bus services are/were provided by a variety of private bus companies. The TrawsCambria livery was based on a common design, including TrawsCambria logos, but with the colours of the base livery selected by the operator running the service. A fleet of modern Optare Tempos were purchased for all but two of the routes, with different specifications for different routes. While not of express coach standard, some of these are significantly more comfortable than normal service buses.
