While on a recent visit, my sweetie and I were lucky enough to have lunch next two very interesting cast members. One was a head engineer for Reedy Creek and the other an imagineer in training. We spoke about many WDW topics, however, I asked why a few years back test track took so long to open. I had heard the rumor that there were sponsor issues with GM. The RC engineer had corrected me by stating that the imagineers working on TT had run into a few problems devising a powerful enough electric motor to power the ride vehicle as well as a full load of guests. Apparantly they sent instructions of what they wanted to the University of Wisconsin. Their engineers worked on the project for several months and came up with the motor currently used and that the power output was roughly 3 times what they had asked for. They were therefore able to put many more bells and whistles on the ride vehicle. We found that to be pretty interesting. You just never know who you'll bump into at WDW.:king:
