Didcot Parkway has 5 platforms and has good visibility of all trains from just one platform. It has a good facilities like food and drink, shops and other amenities. Didcot is now fitted out with LED boards so easier to read all of the train times.
There are lots of high speed trains that pass through Didcot; so be sure to stay away from the edge of the platform!
You can see Didcot railway museum from the station and there is a direct walk through to the museum.
