To travel within Central London you will usually board a tube, whereas you are likely to board an overground while traveling to the suburbs. For example, if you want to take the Harry Potter tour you will take the over-ground.
There are two sections of line where Underground trains and Overground trains share tracks – between Gunnersbury and Richmond, and between Queens Park and Harrow & Wealdstone. That means these are the only places you can change from the tube to the overground. If you are travelling to London, remember, this is an important piece of information.
