Trefnydd, in recent weeks, I've been made aware of the experiences of people on train journeys, where they don't feel safe because people weren't keeping to social distancing and nobody was being reminded to wear masks. My colleague in Westminster Hywel Williams has seen an internal briefing given to Transport for Wales staff that tells them not to enforce social distancing. This is unsafe for passengers; it's also unsafe for people working on the trains. Many people rely on public transport to get to work; they don't have any option but to get onto these crowded trains, and, as we know, masks aren't just to keep the wearer safe, they're principally meant to keep everyone else safe, so, if people aren't reminded to wear masks in indoor spaces, it's other people who are being put at risk. So, I'd like a statement, please, from the Welsh Government addressing these concerns and telling us how they'll make sure that social distancing and mask wearing are taken more seriously by train operators.
