I have maps of the uk dating to the 60s where the railways network and stations were clearly vivble. As Railway use and Green Credentials are seen as very important nowadays I would like to suggest that Bing maps show railways as clearly as Motorways and A roads . At present an overview will let a viewer see easily the major roads he needs to drive but Railways are invisible. In the UK railway uise has returned to 50s levels with 60% of the track. I would submit that being able to see all railways at the same definition levels as motorways can only help the modern traveler.
