The new train is there. I saw it cycling about 2 weeks ago with water dummies. It's a little better themed; hood is more extended and defined, and there are fake tires on the front and back cars. Good news, the bogies are different.
Well, they're on I-40 headed East (The bridge is the old route 66 bridge across the Colorado). However, if they were going to Phoenix why didn't they take I-10? My guess is they're going to the Grand Canyon (watch out for the creepy Flintstones park).
