Creation of a train |
After creation a train, it switchs to the mode idle (curMode).
Set the time for approaching the signal (appTime) to the given value
and send getSignalState to the signal. After receiving newSignalState,
switch to appGo or appStop, depending on the current state
of the signal (signalState). |

| EnvTrainTask2 |
Approaching the signal |
If curMode changes to appGo, restart counting down the appTime.
If curMode changes to appStop, stop counting down the appTime. |
f |
|
| EnvTrainTask3 |
Reaching the signal |
If appTime gets zero, switch curMode to sigStop
or pass, depending an signalState. Set passTime to
the given value. Send the reaching to the track via newSignalReached. |
f |
|
| EnvTrainTask4 |
Changing the signal |
If curMode is appGo and newSignalState (red) is
received, switch to appStop and vice versa. |

| EnvTrainTask5 |
Passing the gate |
While passing the gate, count down passTime. If it gets zero,
send trainPassed to the track and terminate. |
