Locked Re: Creating Signal Mast Logix not understanding Blocks vs. Sensors

Dave,?

Now, I have a better understanding of how SML works.?

I my case, I don¡¯t need or want to place a mast at the turnout throat, the mast will be at the legs. This turnout is one end of a single track main diverging to two destinations with the same for the other end, diverging to two other locations. The masts will be at legs of both turnouts at either end.?

I didn¡¯t realize with SSL when placing a signal head at the throat, at high traffic times, does not take into consideration three trains could be allowed to meet at each area around a turnout. SML will fix that.?

Thanks for the clarification.?
