" They built their own engines there; rather than bringing them back from Central America like the did for Florida. "
Sorta....The 1 and 2 were built by Disney for the park's opening. 3 and 4 are heavily modified baldwins and were added later. Ive heard that they have a fifth engine now from Cedar's Point, but I don't know anything about this engine.
It's a fun operation. Theres a restaurant in Critter Country, I believe called the Hungry Bear Restaurant, from which you can watch the trains cross a wood trestle amongst large pine trees. Makes for some good photos and, if you can set it up to block out the tourist cars, looks more like the Roaring Camp & Big Trees in Northern California than a theme park in LA.
