I'm going to london next week and want to travel up to cambridge one day preferably by train presuming its the easiest and quickest way of doing so. How would i go about planning this,would i need to do it online or could i show up at a station in london to go to cambridge? Iv never been to london so dont know anything really.

You can buy your ticket at the train station in London, you don´t need to book it in advance.
