One final thing. One can type the AtcoCode or the alpha NaPTAN code into this search box to get departure times for any stop in the UK: http://www.nextbuses.mobi/ And an XML API is also available. Details here: http://www.pti.org.uk/nextbuses.htm I notice from the above link that an iPhone app is also available using the service (and of course the codes), so it really is coming together in the UK. Personally I think we should complete the import of NaPTAN into OSM (even for places where no one has specifically requested it). We also need to create a process to monitor divergence between OSM NaPTAN and the version in data.gov.uk (http://data.gov.uk/dataset/naptan ) which is updated every 3 months at present. In summary I think the UK has done a good job on this one and which could be replicated elsewhere!
