There are two trains per hour from Cardiff Central Station to London Paddington. You then need to travel to King?s Cross Station to get your onward connection to Cambridge. To get to Kings Cross, take the eastbound Hammersmith and City (pink) or anticlockwise Circle (yellow) underground line to get to Kings Cross. From there, there are approximately three trains per hour to Cambridge. Allow extra time for negotiating the Underground system. Subway trains run every 2-3 minutes but there are often delays.

The UK train ticketing system is notoriously complicated. It is usually cheaper to buy your tickets up to 6pm on the day before you travel than on the day. And fares are more expensive if you travel before 09:30.
