Find trains from Cardiff to London

To catch a train from Cardiff to London, all you have to do is hop on a Great Western Railway train at Cardiff Central Station and you’ll be there in a relatively short time, arriving at London Paddington Station. On the way, you’ll pass through or make stops at several western England towns and cities. You’ll first go through Newport, crossing the River Usk in the city and on to the much larger River Severn separating Wales from England, where you’ll go over the Prince of Wales Bridge to Severn Beach on the other side. You’ll almost immediately come upon Bristol, with its maritime heritage. A little way farther along, you’ll travel through the green countryside of the southern edge of the Cotswolds Area of Outstanding Natural Beauty, passing near Badminton. This will bring you to the city of Swindon, where the old train station is also the Museum of the Great Western Railway. After this, you’ll go through the scenic North Wessex Downs area, another natural heritage site, before passing through Reading. From here on, you’ll be in the Greater London Metropolitan Area, travelling through Maidenhead, Slough and Hayes, before ending your Cardiff to London journey at Paddington Station.
