What are the best tracks to see via google earth?
Depends on what you are looking to see. most major cities ar good resolution. Chicago and Los Angeles are two cool cities I have looked at. The L.A. ports are interesting. Columbus Ohio is closest to me so I have mapped out the rail lines there and look at train yards and such.
I’m not sure it was Google Earth, but when this feature was relatively new, I located my house. Then I went north to the UP main line in Lombard, and west both west and east, between West Chicago and Proviso. There were over a half-dozen trains, just in that stretch!
I haven’t played with this feature at all lately–I’m afraid it would lead to my never tearing myself away from the computer!
kind of a pointless question… 
the “best” tracks are any tracks you personally are interested in…the “worst” tracks are any you arent interested in…every person will have their own list.
I will never look at any tracks in Minnesota on google earth…because I have never been there and dont care about any rail lines there…likewise you will probably never look at tracks in Western NY…but I spend lots of time looking at them…

Carl, it’s amazing just how much one can see on some of these satellite photo sites. On one, I have pulled up my home and it shows it in perspective form…side, back and front views…! And, in another, I have pulled up a dirrectly overhead photo that shows my John deere lawn tractor parked on the drive way where I locate it each time I finish mowing to clean it off with my leaf blower…Another I found I could see Jean coming out the service door from our attached garage…!
On RR sites to peek at: Might take a look at Horseshoe Curve and on up the mountain to where the tracks go into tunnels. {Near Altoona, Pa.}
