Locking Track

The Locking Track is a special type of minecart track added by the Railcraft mod. It is a combination of the Lockdown, Holding, and Boarding Track. It has several different modes; Train Lockdown, Holding, Boarding, Train Boarding, and Lockdown. The modes can be switched by using a Crowbar on the track.

Train Lockdown
This mode is used to make trains of linked carts come to a complete stop. When this track is given a positive redstone signal it will act as a normal track. When this track is given a negative redstone signal, or no redstone signal, it will stop any train that passes over it.

Holding
When powered by a redstone signal this mode will boost a cart in the direction it was originally heading. When unpowered it will bring the cart to a complete stop, no matter which direction it is going.

Boarding
When powered with a redstone signal, the track in this mode will push the cart faster in the direction it is facing. If a cart moves across a Locking Track in this mode backwards when it is powered, it will either slow down or come to a complete stop. When not powered with redstone, it will not let carts move past them at all in any direction. The direction the track works in can be changed with the Crowbar tool.

Train Boarding
When powered with a redstone signal, the track in this mode will push a train of linked carts faster in the direction it is facing. If a train moves across a Locking Track in this mode backwards when it is powered, it will either slow down or come to a complete stop. When not powered with redstone, or given a negative signal, it will not let trains move past them at all in any direction. The direction the track works in can be changed with the Crowbar tool.

Lockdown
