I've noticed that on this webpage about the upcoming tube strikes, TfL say that the cable car will be accepting LU tickets a measure I've not seen in place before for any reason. This makes it the first time I've ever had reason to think of the cable car as anything other than a bizarrely funded tourist attraction, although seeing as TfL say the Jubilee line will be getting a five-minutely service between Stratford and Waterloo, it remains to be seen how much extra use the ticket acceptance gets the cable car.
