Cardiff Central is the largest and busiest station in Wales, and serves as an interchange between the south and west of Wales, but also offers services to major rail hubs throughout England, including Manchester Piccadilly and London Paddington.
As we had already booked our digital train tickets online, we simply showed them to the railway staff to get through the ticket gates and hopped on our train, which was already at platform 2.
We boarded a Great Western Railway (GWR) train and sat in two window seats with a table in the middle, so we had plenty of space to stretch out and enjoy a few snacks and drinks we bought on board.
