British Trainz

The paid for Pro version of Google Earth with lots of extra features is now free to use .
Download and install from the link (don't fill in registration below link as its not needed !) ,
Once installed sign in using your email address (doesn't have to be registered with Google) and the License Key password is :GEPFREE

I've not looked at all the extra features yet but I do know it includes a ruler to work out 3d building sizes including heights ,
Which will be handy for those who create structures for Trainz

Thanks for that, will come in handy for me, the Google satellite function has been the most useful thing invented for route creation.

It's got Overlays back to 1945 in some areas!
