That's because he used the trainer for the TA2K. you can download them at danimation. I got the "lite" version, and it's cool, you can mow the grass, own all the land, control the weather, control the happiness of guests, etc. The KBF was probably made by using the Drexler patch with the downloads on his site too.
The trainer can be used to make a coaster with other cars, and in different modes. I made an invertigo by using the inverted track and cars with the reversed inclined mode. It's very helpful in creating parks.
