The symbols in the graphic timetable head have a traditional background but have been adapted several times in the meantime. Originally (at least from the 1930s)  was used for a train order change place (station / station with loop) and for train following place ( block post/ block signal). Currently, FBS uses the following extended symbols:

• The symbol refers to a station. The box along the track display symbolizes that in this area there are not only the trough tracks. It begins and ends at the most externally entered points (outer points).
• The symbol shows a station, which has no other tracks than the trough track(s).
• The symbol shows a junction or crossover, that means a train order change place, where trains indeed change the track or the line but cannot perform a (complete) train crossings or overtaking.
• The symbol is an (end) halt, that means a train order change place without points. Here trains can start and end, but not cross or overtake.
• A triangle symbolizes a train following place (block signal or other main signal) in the particular direction. Two of these triangles directly next to each other show the classical block post , which is only correct and should only be used in case of the signals standing directly next to each other.
