If you've ever stopped at your house briefly only to return to your cart and realize a chicken ran off with it, these rails are for you.
When powered these rails act just like your standard Powered Rail , but when unpowered they will grab and hold onto any cart that passes over them. And unlike Powered Rails, the cart can't be pushed off. Additionally, when placed the rail will have an arrow on one side. When an unpowered rail with a Minecart on it becomes powered, it will launch the cart in that direction.
When powered, these rails act just like your standard Booster Rail, but when unpowered they will grab and hold onto any cart that passes over them. However, unlike Booster Rails, the cart can not be pushed off. This rail is very similar to the Boarding Rail, the only difference is that the rail will launch the cart in the direction it was traveling upon arrival rather than a set direction.
