Free Travel On the Gospel Oak to Barking Line

The Gospel Oak to Barking Line (GOBLIN) is offering free travel to everyone that uses it between 31st August and 1st October 2019. This is as a 'thank you' to those who were caught up in the delays whilst new trains were brought into service on the line. I went out to make some journeys to see how it worked, and how I'd get my money back when travelling on it using an Oyster card.
