Similar to the station sign, you can add an optional action to perform after the blocker sign loses power. Options are '''left''', '''right''', '''continue''' and '''reverse'''. If left empty, the train is not moved at all. All actions launch with the same velocity as the train had when entering the blocker sign, no actual launching is performed. The third line is used for a delay, the fourth specifies the direction to launch to.
与 station（车站）控制牌类似，你可以添加一个可选操作，在阻挡器关闭后执行。操作包括 left，right，continue 和 reverse（分别表示左转、右转、继续、后退）。
