Because of the engineering work the trains are all over the place. There is no service between Queen St and Central, so Merthyr, Aberdare and Treherbert trains are being diverted down the City line to Central, some of these trains are stopping at Ninian Park from about 12.30 but not the other City line stations.

There are trains from Coryton but they are only going to Heath Low Level so you have to change to High Level to get to Queen St.

Rhymney trains are going to the bay. Ebbw Vale trains are stopping at Newport with a replacement bus to Cardiff.
