Walt Disney Imagineering has released a video of the first full-speed launch test of a train at TRON Lightcycle / Run in Magic Kingdom. Watch it below or on Instagram.

We’ve caught vehicles push-pull testing and running at a slower speed before now. Push-pull testing means trains are slowly dragged through the entire track of the coaster. After push-pull testing, the trains are launched at incremental speeds, working up to full-speed launches with test weights.
