Can someone tell me are these type 6 and type 8 signals properly placed on the route? I've got some more images coming soon.

The signal for the diverge would be placed before the crossing so as not to obstruct the road.

You mean as in not having the train activate a crossing which would delay traffic?
The diverging signal is placed before the split in the tracks and faces towards the split. By facing, I mean the driver sees the signal light with the back of the signal facing the split tracks. Facing back at the diverging signal, use absolute signals. In real-life, place the signal before the crossing to allow traffic to pass by. With TRC crossings this is possible but it doesn't work with the fixed-track kind.
Signal types, as used by Jointed Rail and N3V:
Absolute signal: Type 04
Permissive or Advanced signal: Type 05
Diverging signal: Type 06
Interlocking signal: Type 08
Signal spacing is a science. The length of the longest train plus train speed will determine how far apart your signals are going to be. If you run lots of short fast trains, the blocks can be shorter. If you run lots of long slow trains, space the signals further apart. Problems arise when there are short trains in long blocks. Sometimes this can't be helped such as when running a shorter passenger train in a territory that supports long trains. There's a term for this but I forget what it is. Something like block dwell time maybe but I'm probably wrong.
With this in mind, if you are running a commuter railroad with lots of short quick passenger trains, you definitely don't want your signals spaced too far apart, otherwise, other trains will have to wait too long to enter a block and this can also be an issue for trains within the block as well.
To allow for more than one train to enter a block, use Type 05, or permissive signals/advance signals (same thing). These have a black bar under the signal head. These signals can be renamed in the program by clicking on the ? in Surveyor when placing the signal down in the track-objects tab in Classic Surveyor. Space the Type 05s so that the trains can fit in between them on a long block.
What this will do is allow a train to enter a block and then be followed by another that will be "riding the yellow signals" as they say. The following train will operate at half the posted speed as the driver prepares to stop at the next signal should the next permissive signal show a red. If a permissive signal shows red, then the following signal is a stop. In real life, the driver will contact the dispatcher for permission (permissive signal) before entering the block, but since our AI don't have that ability and continue to drive. The advance signal will show what signal is coming up. This is seen while driving a block and there's a green signal followed by a yellow, followed by a red advanced signal indicating that there's a red signal or some other obstruction such as a junction set against the driver.
Diverging signals, the ones with two heads or Type 06 will indicate a red signal for the line that's not used and an aspect for the line that is. If the signal is green, the driver continues at the posted speed while some other aspect indicates the signal head such as yellow.

So are the signals as configured proper?
Yes, the JR signals are. Use them as is and they work fine.

There is one signal that's giving me problems. It claims the signal ahead is in an unknown state. What can I do to fix that?
norfolksouthern37
what's a normal map?
It means that it does not understand the state of the next signal and therefore cannot make a determination; The next signal currently has an internal state not recognized by this one. To fix it make sure the next signal is working properly and isnt giving a confusing state.
