> > The signalscr.trk scenario is a very simple example of how to create customized signals using scripts. The leftmost signal is associated with the rfi_avv.tds file. This script describes the behavior of an advance signal as defined by RFI (the Italian Railroad Infrastructure Company). The script tells the signal to change its aspect based on the condition of the next signal and of the switch after the next signal. As you clear the protection signal to let T1 go to B, you'll see that the advance signal automatically becomes green. Once you throw the switch and clear the protection signal to let T2 go to C, you'll see the advance signal to start flashing. |  |
