Local authorities should be more interested in your help because of 
the financial pressures.  I will be happy to try and follow up through 
Traveline channels if you have good feedback that is not being taken

NaPTAN is now released on data.gov.uk every three months so the feed 
into OSM is rather out of date now.  That will affect some areas more 
than others.

I will like to compare the OSM details with the current NaPTAN and 
will try to do so soon.
