Train services on the Vale of Glamorgan Line will be affected by engineering works in the coming weeks.
Transport for Wales says there'll be no rail services this Sunday morning (29th September) as work is carried out between Penarth, Barry Island and Bridgend.
Trains will be replaced with buses until the line is due to reopen at 12.25pm.
The line also be closed the following Sunday (6th October) - on the day of the Cardiff Half Marathon - with passengers from Llantwit Major and Rhoose being advised to take a replacement bus to Barry or Bridgend where they can catch the train or make their own way to those stations.
On the same day, passengers from Barry Island and Penarth heading to the Welsh capital will be able to catch a train in time for the start of the half marathon, after TfW reached new agreements with train crew working on Sundays.
Services from Barry Island will run to Cardiff Central at 8.09am and 8.49am with a train from Penarth starting at 8.45am ahead of the half marathon's 10am start outside Cardiff Castle.
More disruption's expected on Sunday 27th October, when Barry Island and Bridgend services are affected due to separate engineering work between Cardiff Central and Bridgend via Pontyclun, operating at reduced and altered frequencies to accommodate diverted trains.
Services between Penarth and Cardiff Central are currently operating at a reduced frequency - every half hour - on weekdays.
Further details on disruption can be found on the TfW website.
