How Block Signals Work
The following example shows for blocks A to D, which are subsequently passed by two
trains.
Diagram 115: Block Signals
The internally calculated signal aspects are indicated inside the black rectangles below
the block name. These signals are also indicated as cab signals in the Train Window,
while the train is inside the relevant block. Above the track there are signal elements
controlled according to these aspects. For example the block signal labeled “B” is assumed
to belong to block B.
Train 1 may enter block B but not block C, because block C is still reserved and occupied
by train 2.
The calculated block signal for train 1 in block A is green, because train 1 may leave
block A and enter block B without any restrictions. This is also indicated by signal A,
which is assumed to belong to block A.
Since train 1 must not enter block C, the block signal of block B is calculated as red (in
this case an advance signal is not indicated in the Train Window). This state is indicated
by signal B of block B.
Train 2 may leave block C and enter block D only with restricted speed. For this reason
the calculated block signal for train 2 in block C is yellow. This state is indicated by
signal C, that belongs to block C.
Additional Notes
The internal signaling system of TrainController does not claim to simulate realistic
signaling systems of the prototype. For each block the software only calculates,
