Urgent repairs to a bridge are still causing disruption to rail services through Cardiff.
Services on a number of routes have been cancelled or suspended since Easter Sunday due to repars on a defect at Queen Street.
Network Rail says the work is continuing and disruption is expected to continue until the end of Tuesday.
Among the services affected are Transport for Wales' routes from Barry Island to Caerphilly, from Penarth to Cardiff Queen Street and from Cardiff Central to Cardiff Bay.
A TFW spokesperson said: “Due to a bridge defect between Cardiff Central and Cardiff Queen Street disruption is expected on the Core Valley Lines and on mainline services between Cardiff Central and Newport until the end of Tuesday 22nd April.”
”Engineers are currently on site and rail replacement transport is being sourced to assist customers in completing their journey.”
Great Western Railway and CrossCountry services to and from Cardiff Central are also affected.
Replacement buses are running from Cardiff Central to Newport and Caerphilly.
