When pushing a minecart towards a corner rail, depending on its orientation (shape) and the direction the minecart is going, it either bounces back as if it (the corner rail) was a full block or deataches form the rail.

 Build every corner shape and push a minecart in both directions.

Orientation (Shape atribute):

• north_east
  • Direction the minecart is going:
    • South to east: Normal behaviour
    • West to north: Normal behaviour
• north_west
  • Direction the minecart is going:
    • South to west: Minecart deataches
    • East to north: Minecart bounces back
• south_east
  • Direction the minecart is going:
    • North to east: Minecart bounces back
    • West to south: Minecart bounces back
• south_west
  • Direction the minecart is going:
    • North to west: Minecart bounces back
    • East to south: Minecart bounces back
