Be Patient! There are hundreds of gifs in most scenes, and there is also scripting to be read and executed, so the scenes take some time to load, even under broadband conditions. It is probable that you'll see odd things -- trains off the tracks or in the sky -- so just be ready to hit the Refresh button a time or 2.
The most recent scenes contain a couple of hundred gifs, and the trains are spaced out to give quite a bit of variety. Be ready to watch for up to a half hour before all trains have been viewed.
