Just to bring this up to date. At the same time as asking for the number of people using each actual OSI pair, I also asked for data for Manor House to Harringay Green Lanes. It’s being used by 20-40 people a day in both directions with a 4-week total of 874. This would put it 102nd out of 123 OSIs (once duplicate station codes have been agregated). It’s not as big as the other case I’m looking at – more on that in a day or so – but I’d still support it being added.
