As part of the CymruExpress launch, Arriva returned the TrawsCambria Optare Tempos and replaced them with Wright Pulsars (on services 40 and 50) and a pair of Van Hool Alizée coaches (for use on services 10 and 20). The Pulsars were initially planned to be an interim measure, until new Wright Eclipse Gemini double-deckers could be introduced in August 2012. However, these were never introduced. The decision to operate the CymruExpress routes commercially prevented the introduction of the TrawsCymru TC1 service.
