Transport for Wales (TfW; Welsh: Trafnidiaeth Cymru; TrC), is a not-for-profit company owned by the Welsh Government and managed at arm’s length by its appointed board. TfW oversees the Transport for Wales Group (TfW Group) consisting of itself and its subsidiaries; Transport for Wales Rail Limited, the train operator of the Wales & Borders railway franchise, and TfW Innovation Services Limited; a joint venture between TfW (51%), and former operator KeolisAmey Wales (49%).

TfW contracted KeolisAmey Wales in 2018 to run using the trading name Transport for Wales Rail Services. Due to a fall in passengers caused by the COVID-19 pandemic, a Welsh-government owned company, Transport for Wales Rail Limited, took over the day-to-day operations of the franchise on 7 February 2021.

It was established to provide support and expertise to the Welsh Government in connection with transport projects in Wales. In 2017, it procured the new Operator and Development Partner for the Wales & Borders railway franchise[8] under powers delegated to the Welsh Government under the Government of Wales Act 2006.[9]

The company introduced the Transport for Wales brand to replace the now-defunct Arriva Trains Wales brand on the Wales & Borders franchise from 14 October 2018. The franchise was fully operated by KeolisAmey Wales.[10][11][12]

In Summer 2020 the Welsh Government withdrew the Bus Services (Wales) Bill that they were developing, which would have provided local councils with the statutory power to franchise bus routes in Wales. This was because they aimed, as part of other reasons “to utilise Transport for Wales as the main delivery and procurement body for the bus system, transferring the roles from local authorities, in return for the local authorities becoming part ‘owners’ of TfW”.[13]

On 22 October 2020, the Welsh Government announced that the Wales and Borders rail franchise was to transfer operations to a Welsh-government owned rail operator of last resort, due to the COVID-19 pandemic, all staff, operations, and branding were transferred to the new company on 7 February 2021.
