What's the difference between Launch, Trim, Coast, and Stop modes?
Launch accelerates carts to maximum speed, Trim gently slows them down, Coast lets them roll freely, and Stop holds carts in place until a redstone signal releases them. Chain these modes together in a 
Linear Motor Controller to build complex ride sequences.
Linear Motor Controller to build complex ride sequences.How do I detect the exact speed of my coaster cart?
Use a 
Coaster Observer block placed near the track—it reads cart speed in Blocks per Second and outputs an analog redstone signal lasting 10 seconds. You can display this value with Display Links or Engineer's Goggles.

splashdown scoop slowing down the cart?
Make sure the scoop is mounted to the cart's bottom and the track section is fully submerged in water. The water brake only works when both conditions are met.
How do I build a multi-pass launch like a real roller coaster?
Chain multiple Linear Motor Controller steps together—use Launch to accelerate, Coast to let the cart climb, Trim to slow it at the top, then repeat. See the Multi-Pass Launch Sequence guide for a full walkthrough.

The cart held by that motor step will be released and move to the next section controlled by the Linear Motor Controller.
Linear Motor Controller.Can I see motor power usage and cart speed in real-time?
