What's the wheel arrangement of these locomotives?

All 3 of them are 2-4-2T wheel arrangements.

Thank you!

Well, when the park first opened, they had the Discovery River boats that guests thought were supposed to be transportation around the park. There's two loading docks, one at the front of the park, and one back between Africa and Asia. The boats made a round trip, passing by the other dock while guests there wondered why the boat didn't stop. The queues got so backed up that it would become well over a two-hour wait. And yes, there were things to see along way: Dragon Rock, the cave with flames shooting out of it, the geysers...and there may have been more.

Then they decided to make it into a "Radio Disney cruise", which turned off a lot of guests. They would bring these "experts" onto the boats with small cages or boxes of smaller animals or insects, hoping to "teach" people about conservation, etc. They finally got rid of them early on in the park's history.

Let me see if I can find a link to what happened to the boats:
Here's a WkiPedia entry: http://en.wikipedia.org/wiki/Discovery_River_Boats

Is the flame shooting cave still there and operating? It was the last time I went to Animal Kingdom 11 years ago.

Still there? Yes. Still operating? No. There isn't a good way for anyone to see it anyway since they closed the boats.

I agree it would have been nice to have the railroad as transportation around the park, because the park is so big. It would be nice to not have to walk all the way to Everest or the Safari. To me Disney seems to be making major changes and improvements to their parks lets hope that Animal Kingdom will get a little Imagineering TLC. I recently thought that if Disney wanted to add a North American section to the park, like over by camp Mickey, Disney could do a new version of the Mine Train through natures wonderland.

I can see Sam's ears perking up.
