📋 About This Mod
Adds Polish Signals to Derail Valley via the Signals Framework
You ever played SimRail? You live in Poland? You just want different Signals? Then this Pack is for you!
I present you today the Polish Signal Pack!
This Signal pack is as accurate as it gets while still considering the gameplay aspect of Derail Valley.
It is recommended to play with "Enable Special Matching Path" ON in the "DV Signals" mod settings, but OFF is also supported.
The Setting "Require Reserving Signals to Clear" can be ON or OFF, depending on your playstyle. ON will require you to reserve every signal you want to drive through.
Installation instructions
Just install this zip via UMM or DVMM and select "PLSignals" as your Signal Pack in "DV Signals" mod settings.
Requirements
DV Signals
This Animation should explain all possible Aspects that a Signal can have:
If you like reading and want to get a more deepdive of the logic, continue below:
This Signal Packs differentiates between Main Signals:
Road Signal
Entry Signal
Exit Signal
Also between Distant Signals:
Distant Signal
Repeater Signal
And also between Shunting Signals:
Shunting Signal
Major Shunting Signal
How a signal behaves, depends entirely on what type of signal you are approaching, but the basic rules still apply (The possible signal aspect names will be shown in parentheses):
Basic Rules:
Top 3 Lights of any Main Signal functions mostly like a traffic light:
Green: Go as fast as the track allows (can be S2, S6, S10 or S10a)
Yellow: Expect Stop on the next signal (can be S5, S9, S13 or S13a)
Red: Stop (can be S1 or Sz)
The first two lights can also flash:
Green Flashing: The next signal points to a fast (60km/h or above) junction path (can be S3, S7, S11 or S11a)
Yellow Flashing: The next signal points to a normal (40-50km/h) or slow (10-30km/h) junction path (can be S4, S8, S12 or S12a)
Diverging Light:
The bottom yellow light (4th from top) only activates if the junction you are approaching is in a diverging position. Do with this information what you want since its not entirely consistent in Derail Valley (if its right or left) but usually points to the slower path.
Speed Bar:
Then there is the Speed Bar (3 lights horizontal aligned below the main lights). Here it shows you the speed for THIS signal and ONLY if the path is DIVERGING (bottom yellow light is lit):
Green Bar: 60km/h or above (can be S6, S7, S8 or S9)
Yellow Bar: 40-50km/h (can be S10a, S11a, S12a or S13a)
No Bar: 10-30km/h (can be S10, S11, S12 or S13)
The speeds are reduced from the original system to make it a better fit into the Derail Valley Network.
Note to Road Signals:
If you encounter a Red Road Signal and want to pass it, use the Comms Radio to Reserve it. It will align the switches for you. If it then is still Red but the White Light blinks (called Sz), that means that this track is actually occupied and you enter at your own risk!
Entry and Exit Signals:
Those have the addition "m" to them which means that they can show a shunting aspect.
You can get a shunting clearance by reserving an Entry, Exit or Shunting Signal with the Comms Radio!
If Entry/Exit Signals point to any track that is occupied, they will show Red. Once you've got your shunting clearance, they will turn White, allowing you to proceed ON SIGHT.
Damage caused during shunting cannot be blamed on a signal fault. You have been warned.
Shunting Signals:
Those have a Blue and a White light.
Blue: Stop (Ms1)
