• During the mid-2010s, as Arriva Trains Wales' 15-year franchise period came towards its scheduled end date, the process to select a successor was started. In October 2016, Abellio, Arriva, Keolis/Amey and MTR Corporation were shortlisted to bid for the next franchise. During September 2017, the formal Invitation to Tender was issued.
• During October 2017, it was announced that Arriva was voluntarily withdrawing itself from the tendering process; the decision was reportedly viewed by some politicians as having raised questions about the franchise process. In February 2018, rival firm Abellio also opted to withdraw, which was largely due to its partner company Carillion having effectively collapsed and entered liquidation one month earlier.
• On 23 May 2018, it was announced that KeolisAmey Wales has been selected to operate the next Wales & Borders franchise, which was set to run for 15 years, following the expiry of Arriva Trains Wales' franchise.
