I am delighted to be able to launch an alternative to the TfL Single Fare Finder. It is linked at the top of the Fares Guide page, or you can access it here.
Like the TfL version you enter two stations, but that’s where the similarity ends. The results page contains all the different fares (Adult, 11-15, 16-18, Disabled Railcard and Other Railcards). At the top of the results page is a button to simply reverse the enquiry so you can check any differences in peak times.
The fares data is provided directly by TfL Open Data so is the same as that found on their single fare finder. The list of stations has been sanitised so that multiple entries for the same station are eliminated. No distinction is made between National Rail, London Overground and TfL Rail – they are all NR.
