Track circuit breaks must be manually set by the user. Signals must be assigned to track circuit breaks and to a direction(connid).
To simplify the whole system, there is no overlap.

== Database storage ==
The things that are actually saved are the Track Circuit Breaks. Each TCB holds a list of the TCBs that are adjacent in each direction.
TC occupation/state is then saved inside each (TCB,Direction) and held in sync across all TCBs adjacent to this one. If something should not be in sync,

It will be necessary to join and split trains using call-on routes. A call-on route may be set when:
- there are no ROUTE reservations
- there are TRAIN reservations only inside TCs that have "allow call-on" set
-

+== TC Properties ==
+Note: Reversible property will not be implemented, assuming everything as non-rev.
+This is sufficient to cover all use cases, and is done this way in reality.
+ REVERSIBLE - Whether trains are allowed to reverse while on track circuit
+ This property is supposed to be set for station tracks, where there is a signal at each end, and for sidings.
+ It should in no case be set for TCs covering turnouts, or for main running lines.
+ When a TC is not set as reversible, the OWNED status is cleared from the TC right after the train left it,
+ to allow other trains to pass it.
+ If it is set reversible, interlocking will keep the OWNED state behind the train up to the next signal, clearing it
+ as soon as the train passes another signal or enters a non-reversible section.
+CALL_ON_ALLOWED - Whether this TC being blocked (TRAIN or ROUTE) does not prevent shunt routes being set through this TC
== More notes ==
- It may not be possible to switch turnouts when their TC has any state entry
