In September 2019, the shareholders of the cross-Channel high speed train operator [[Eurostar]] and Thalys introduced a plan to merge the two companies, named project ''Green Speed''. Both companies already operate in France, Belgium, and the Netherlands, with Eurostar also operating in the United Kingdom, and Thalys also operating in Germany, while SNCF already held a [[majority stake]] in both operators. The project was promoted as reducing costs and providing a more seamless experience to passengers via the use of a single [[Electronic ticket|ticketing system]] and [[loyalty program]].<ref>{{Cite web |date = 27 September 2019 |title = Eurostar-Thalys merger proposal revealed |url = https://www.railjournal.com/passenger/high-speed/eurostar-thalys-merger-proposal-revealed/ |access-date = 2 May 2022 |website = International Railway Journal |language = en-GB}}</ref><ref name="EurostarThalys" />

During September 2020, the merger between Thalys and [[Eurostar International]] was confirmed,<ref>{{cite web |url = https://www.businesstraveller.com/business-travel/2020/09/16/eurostar-and-thalys-to-merge-in-2021/ |title = Eurostar and Thalys to merge in 2021 |work = Business Traveller |date = 16 September 2020 |access-date = 5 January 2021}}</ref><ref name="RailGazette" /><ref name="RailMag" /> In October 2021, it was announced that, upon the completion of the merger, it was intended for all of Thalys's services to be rebranded as Eurostar.<ref>{{cite web |url = https://www.railwaygazette.com/high-speed/eurostar-brand-to-remain-after-thalys-merger/60033.article |title = Eurostar brand to remain after Thalys merger |work = Railway Gazette International |date = 5 October 2021 |access-date = 5 October 2021}}</ref>  On 28 March 2022, the [[European Commission]] approved the merger.<ref>{{Cite web |title = Competition Policy |url = https://ec.europa.eu/competition-policy/index_en |access-date = 30 March 2022 |website = ec.europa.eu |language = en}}</ref> The rebranding of Thalys services commenced in the autumn of 2023, and was planned to be completed by early in 2024.

The change of logo on the trains took time to complete; during a transition period, some PBA/PBKA trains with the new "Eurostar" logo could be seen together with others still wearing the older "Thalys" logo.
