Railroad Switch Control

The Railroad Switch Control is used to decide the path of a manual driven Train on a Railway switch. Its appearance is based on the number of connected tracks.

Usage
It is generated automatically on every railway switch that is properly built. It cannot be built separately, dismantled, or moved by any means.

A railway switch is formed by joining two Railways together at the end of a segment. It cannot exist immediately following or preceding a Train Station. Multiple tracks can be connected to the junction, the only limit being building space (therefore, it is possible to make a 15-or-more-way junction).

If the Railroad Switch Control doesn't appear, the track is not connected properly and the switch will not work.

Switching the switch is only doable by hand and it only affects trains with autopilot disabled. Automated trains ignore Railroad Switch Controls and always choose the correct track automatically, even if the switch is switched by another automated train.

Current issues

 * There are two major problems with switches which only occur after the switch is built:
 * A single Railway segment can only have a switch on one end, not both, otherwise autopilot paths through the junction incorrectly.
 * A similar problem can be observed with X shaped (n:m) junctions.
 * Automated trains change the switch control setting without actually changing the physical appearance of the control. A manually operated train, approaching a switch that normally would take the train left will actually send it right if an automated train had passed through that control and went right. This is adjusted in an undocumented patch, probably in exprimental (0.4.x). Now the automated trains even switch the physical appearance of the control. (Tested in 0.4.0.10)
 * The 'flag' of the Railroad Switch Control does not necessarily point toward the direction of the split it is leading to, instead, it depends on the build order. This is adjusted in an undocumented patch, probably in exprimental (0.4.0.x). Now the 'flag' of the Railroad Switch Control does point toward the direction of the split (Tested in 0.4.0.10)
 * As the switch defaults "left" in appearance upon being built, it is advised to build the left track first before the right track. However, this is purely visual.
 * The rod part of the Switch Control does have a hitbox, but it only corresponds to state 1.

History

 * Patch 0.4.0.4: Fixed “Floor is too steep” appearing when railway switch controls were placed in between foundations
 * Patch 0.4.0.x: Undocumented fix before 0.4.0.10 The "flag" for Railroad Switch Control better shows actual position of the switch
