== Activation Direction == By default signs only activate when the train ''sees'' the front or sides of the sign. This means you should place signs facing the direction of train movement. To override this behavior you can set these activation directions by adding a colon (:) followed by one or more [[Special:MyLanguage/TrainCarts/Signs/Direction|directions]]. If you want the sign to always respond, just use '''[train:*]'''.
默认情况下，只有列车看到控制牌的正面和侧面时，控制牌才对列车有效。这意味着控制牌面对的方向应该是矿车驶来的方向。要覆盖此功能，你可以在第一行添加（:）英文冒号后跟一个或多个方向。如果你想让控制牌响应所有方向，可以使用 [train:*]。
