An OSI is an 'Out of Station Interchange' on the TfL Network where you can leave one station ... and walk to another but it charges as you as a continuation, rather than two separate fares.
There are only certain places on the system where you can do this, and I thought I'd try a journey that included as many as possible ... and explain how they worked as I went.
Can I get from Harrow & Wealdstone to Barking by a very convoluted route and only pay for one fare?
