Mods/TrainCarts/Signs/Blocker

Introduction
The blocker sign allows you to block trains coming from a certain direction. It is also used during path finding to block certain routes from being used. For example, if your trains are getting sent into the wrong direction, possibly colliding with other trains, you can use the blocker sign to prevent this.

The sign needs to be powered for it to function. It does not have to be powered for it to be used during path finding. It operates on both flat and ramped rails, so it allows you to stop a train while it slides down a ramp. Players can not push the train past the blocker sign, but they can push it the other way since that direction is not blocked.

Therefore blocker signs do not indefinitely freeze the train until power is removed, you can still push it in the other direction.

Third line
You can use the types defined below or keep the line empty. If left empty, the train has to face the text-side of the sign to be blocked. The type is defined by the first letter, so instead of right you can also use r on the line.
