Jim,
?
You have a single track so you have to protect against the train in B1 moving into B2.? To do what you want I think you¡¯d have to add directional logic.? Others may know better.

Hi, not sure if I have a problem or just a complete lack of understanding of signal masts.
I have a very simple panel with 3 signal masts and two blocks
Sm1?????????????????????????????????????? sm2???????????????????????????????????????? sm3
? #-------------------------------------#--------------------------------------#
???????????????????? ?B1???????????????????????????????????????? B2
The signal mast logic for SM2 is be green if B1 is unoccupied.
The signal mast logic for SM3 is be green if B2 is unoccupied.
If B1 is occupied and B2 is unoccupied? SM2 and SM3 both go red. Is this correct (I was hoping that only SM2 would be red and SM3 would remain green).
Thanks
Jim
