Following a Welsh Assembly Government consultation on improvements to the TrawsCambria network, in 2010, a programme of improvements for TrawsCambria services X40 and 704/T4 was announced. New buses were the main improvement identified. These would be equipped with coach style seating, greater luggage space, real time information and WiFi. The Welsh Assembly Government decided these upgraded routes, and eventually the network as a whole, were to be re-launched under the new TrawsCymru brand. As part of the re-branding, service X40 was to be re-numbered TC1 and T4 would have become TC4. The T4 upgrade and re-branding went ahead, but without the planned renumbering to TC4.
