Cardiff Parkway railway station

Cardiff Parkway () is a planned railway station in the eastern region of Cardiff, and near to the boundary with the neighbouring city of Newport. The station is privately funded as part of the wider Cardiff Hendre Lakes business development.
Origins.
Cardiff Parkway Developments Ltd had applied for a station as part of the New Stations Fund 2, but it was unsuccessful. The station is to serve a new business park and would fit in with the proposed South Wales Metro. The new station is to be located south of the existing St Mellons Business Park in Cardiff, with the location of the station between Newport Road and Newport stations.
On 13 July 2017, it was announced that the station would be privately built rather than public and would not need the same system of approval than if it was publicly built.
On 19 July 2017, it was announced the station had received funding of £30 million and was due to open in February 2020. The station is expected to cost around £120m and aims to secure 8 services an hour to Cardiff and Newport, as well as mainline services to other parts of the UK, including London and Bristol.
The plans are to skew the two relief lines to the south to allow an island platform to be built in the middle of the four tracks, plus platforms on either side. The station will initially be served by Class 170 diesel multiple unit trains and eventually by brand new Stadler FLIRT diesel-electric multiple units, which will operate on the Maesteg South Wales Metro line. 
If Cardiff Parkway opens it will be the first station between Cardiff and Newport since Marshfield Station closed in 1959.
Construction.
In January 2019, it was revealed that the station will open in 2022 with construction starting in 2020. A planning application was due in 2019.
In November 2019, a four-week period of public engagement into the project was launched. Completion of the station has been pushed back to 2023, subject to a planning application due in 2020. In August 2020, a report suggested construction would start the following year, and the station would open in 2024.
