Several train services in Wales this weekend have had to be cancelled, delayed or rerouted due to a lack of staff availability.
Transport for Wales have issued an apology for the cancellations, explaining that some colleagues are self-isolating, shielding, caring for someone or are subject to a positive Covid test result.
The organisation has advised customers to check before travelling and said it anticipated "some challenges over the coming weekends" as Covid cases across Wales continue to rise.

It comes as 35 train journeys have been cancelled as of an update at 13.58pm on Sunday on their website.
The majority of cancellations are for trains travelling from Cardiff.
There are also updates for 35 train services, including delays, early terminations, and replacement train and bus services.
A Transport for Wales spokesperson said: “We would like to apologise for any cancellations this weekend. Unfortunately, some services have had to be cancelled due to train crew availability.
“Like many organisations employing large numbers of people, we continue to experience the impact of Covid-19 with some colleagues having to self-isolate, shield, care for someone or are currently subject to a positive test result.
“This week, we were able to make some changes to our Sunday timetable in advance, to allow customers to plan their journeys. We always advise checking before travelling; customers can do this via our Capacity Checker and our Twitter account.
“We envisage some challenges over the coming weekends, especially on Sundays. We are working hard to minimise any service disruption and we continue to advice customers to check before travelling.”
