Wow!! A group seems to have developed an overlay of Google maps that shows the Swiss Trains in real time. It's not yet GPS driven but since the trains in Switzerland are always on time, the programming assumes their location. You won't believe what you are seeing. Enter any city or train number into the system and it goes there. Put you mouse over a train in motion and it will tell you all about it. Move your mouse over the red rectangles with white arrows and the train station is identified. It is based on the Swiss train schedule but this organization does not seem to be affiliated with the Swiss train system. I can't stop playing around on this website.
The website is www.swisstrains.ch or CLICK HERE to see it. Your thoughts on this new type of information are welcome. Larry
