Alright, so I want to create a ride kind of like Indian Jones at Disneyland Resort. I need the car to speed up and slow down at specific times. Is there anyway I can do that? I've seen videos on the internet and it looked like people have used brakes but set the brakes at a higher speed than the train, but when I tried it, it does not work at all. What are some of your methods or something I've missed that I should do.

There are boosters, if that's what you're looking for (In fact, they SHOULD look just like brakes)... Otherwise, you can always speed it up when you edit the video.

are you using block brakes if so use regular brakes
