I am attempting to make a MC roller coaster -witch I have done before- and for some reason when I power the tracks, the mine cart shakes back and forth and won't move forward or let me ride in it. I currently am playing 1.8.8 for the PC

  • Is the Minecart bouncing off of two blocks? Is it shaking as in going along the rail, or as in shaking side to side?

    Are you sure you're using powered rails instead of activator rails?

  • Alternatively, what button are you pushing to try to get in the cart? Left click attacks and causes the minecart to shake back and forth until it breaks into a pickup. Right click is what you use to get in (by default). Oct 25, 2015 at 2:43
  • @DGarvanski you should make that into an answer.

Since the 1.8 update powered rails and activator rails behave differently when used for powering a mine cart track. Using activator rails causes shaking and, sometimes, ejects the player character from the mine cart. You only need the activator rails to activate carts, but they shouldn't be used continuously. Powered rails should be used for increasing or decreasing speed.

As provided by Mystery, here is a video demonstrating the changes made to mine carts and the usage of different rails:

    Maybe include this link in your answer: youtu.be/nW67NTP7sro In the video, the changes to minecarts are shown. Also it covers the "bouncing back and fourth", Kirklandish mentioned
