Easter Day 2024. Having stayed across the channel for a few days we went to Heath Evangelical Church in Cardiff for the Easter Day service and stopped at Cardiff Centra station on the way. As at some other station we had to speak to one of the staff to get access to the platforms, which necessitated explaining which, and he helpfully told us a bit about the station. This included menion of the fact that there is a platform 0 (zero), 

The corridor leading to Platform 0.

Platform 0 itself.
