Some very interesting usage figures by station published today by Transport Scotland. Overall journeys are still around 20% higher than anticipated but there are some stations well ahead of expectation and some well behind.

What the data shows is that in general demand has been lower than expected in Midlothian, perhaps the pricing here relative to the good quality Lothian Buses service hasn't quite been chosen correctly. Shawfair is a special case in that less development than expected has taken place so demand will take awhile to build.
In Edinburgh demand for travel to the line is broadly as expected.
In the Borders meanwhile the demand level is much higher than anticipated (5 to 10 times beyond what was expected).
I think an interesting number may be the differential between Tweedband (10 times higher) and Stow / Galashiels (5 times higher). The higher Tweedbank numbers may reflect the initial excitement, one off trips to try out the new line and possibly even the bargain fares mistake found by forum members and others.
However it looks like the figure of 5 times higher than expected numbers at Stow and Gala may reflect a genuine long term underestimate of demand for rail travel from the Borders. In the longer term I'd expect the Tweedbank figure to fall back to more like that seen at Galashiels but still stay well above expected demand levels.
