a shuttle service between Cardiff Queen Street and Cardiff Bay every 12 minutes Monday to Saturdays (between 0630 and 2330) and every 12 minutes on Sundays (between 1100 and 1630) using Class 153 Sprinters. Some services were operated by a Class 121 "bubble car" until it was withdrawn in June 2013. Modernisation In June 2018, the then future Welsh train operating company KeolisAmey Wales announced plans to build a line extension and a terminus station, The Flourish (since renamed back to Cardiff Bay) for the Butetown Branch, along with an intermediate station at Loudoun Square. This station would have completely replaced the existing station, which would have closed. Plans have since been revised, and in August 2022 it was proposed to construct the two-platform Loudoun Square station further to the north, and to retain Cardiff Bay station in its present location, but to add a second platform. The station will be served by more frequent tram-train vehicles from spring 2024. The line will form part of the South Wales Metro.
