Love it, especially the little escalator to get up the ramp. I don't think it would work here because...
1. It can't take wide tyres, if it did then bikes with narrow tyre would probably fall over.
2. It costs £13 a month, why spend that when railings are free and legal.
3. There won't be many of them and nobody rides a bike to park it a long way from where they work.
If I was a train commuter I would be tempted to keep a cheap bike in it to ride between the station and the office and then chain it to the railings, that kind of defeats the object though.
