I'll happily write to them all, but...

Does anyone know if there's a best approach for lobbying / campaigning against the loss of our direct Charing Cross services (most critically, in my opinion, southbound late evening services - if that could be a possible compromise)?

Should we write independently to the people se23northener mentions or is there a better way of galvanising the pressure? If writing, are there specific points to raise which would be likely to demand more attention from the addressee?

Are there case studies of successful campaigning in similar situations?

Or is it completely pointless to waste the effort even trying?
