Getting from Cardiff to London by train

Review by Paola Labib

After spending a great weekend in the Welsh capital, we walked back to Cardiff Central station from the city centre for about five minutes. 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.

We got from Cardiff to London in less than two hours, stopping only at Newport, Bristol Parkway, Swindon and Reading before reaching London Paddington station. Once we arrived, we climbed down the stairs towards the underground station entrance and hopped on the first Circle Line service we found to get to Farringdon.

Overall, our journey was pretty smooth and comfortable. I highly recommend taking the train from Cardiff to London – you’ll get from one city centre to another in no time, plus you won’t have to worry about parking.
