Here are some of the new coaster trains, and the coasters I think they are from
(that is… speculation)...

Here we have the Sloth Cars for the suspended coaster… how you are meant to figure out they are sloth remains to be seen!!

To the left is the Limousine Rollercoaster, and to the right a
to the right. And of course the whale cars to the right. :-)

These show the TGV Coaster. (European Themed)

Look carefully in this station and you can just about make out what look like new cars on the Water Coaster (they are Manta Rays)

To the left are Sputnik Cars for the Single Rail inverted coaster (Russian Themed). And to the right is the bear coaster. (for some strange reason it looks like one of those bear skin rugs).

The Surfing Coaster (Australian) to the left and on the right is one of the most imaginative rides I've seen yet, the Ostrich Coaster.

Here are the coach trains for the wooden coaster, a nice addition to any Western Themed Park

And the long awaited dragon trains, why these didn't appear in any of the previous games is a mystery.

I'm going to continue referring to these as Snowball trains, or puffballs, or if you squint and look sideways, doesn't that front one remind you of the Marshmallow Man from Ghostbusters? Anyhow, it is Antarctic themed either way.

And finally… new train fro the Giga Coaster??
