The list below identifies actual Transport for London stations, however there are also numerous impostors. Use the letter "r" to identify real stations and the letter "f" to identify fake stations. Time is limited because there are only two possible single-letter answers per item.
Some of these "real" stations are Docklands Light Railway stations, and some are London Overground Stations - so the quiz title is a little misleading!
Something needs to be changed. The way it is now, you can get no wrong answer, because when you type the wrong letter it is not accepted and you know you have to type the other one. That way, even though I had many wrong at first try, they were all counted as correct in the end.
