Main Signal (主信号)

Lights	Tag (railway:signal:...)	Description
✖️⚪️ 🟡🔴	main=CN-ExOSShD:XYORmain=CN-3:XYANDmain=CN-ExOSShD:WRORmain=CN-3:WR	if it's known for it's 3 display on 25Hz track circuit, ExOSShD is for it's display style name but in my opinion it's too long so meh, go for -3
🟡 🟢 🔴	main=CN-ExOSShD:YGR main=CN-3:YGR	this signal should be as 3 display.
🟡/🟢 🟢 🔴/🟢	main=CN-ExOSShD:LGO main=CN-3:LGO	this signal should be as 3 display, with ability to show GG for secondary route.
🟢 🔴 🟡	main=CN-4:YGR	this signal should be as 4 display, with ability to show GY for STFD

Distant Signal (复示信号)

Lights	Tag (railway:signal:...)	Description
🟢 🟡	distant=CN:GY	This is not going to show red, it's not main signal sir.
. ⚪️ ⚪️⚪️ in △	distant=CN:WWW
🟢 in ◇	distant=CN:G
⚪️ in ◇	shunting_distant=CN:G	NEW!! for railway:signal:shunting_distance tag

Shunt Signal (调车信号)

Lights	Tag (railway:signal:...)	Description
⚪️ 🔴	shunting=CN:WR	since cannot sure 3/4 display it is then not tagging which system is better if you know it then you can use railway:signal:shunting=CN-3:RW and so on
⚪️ 🔵	shunting=CN:WB

Other Property Tag

Since the shunting signal might be on side or below the main signal,railway:signal:shunting:heightis required more then dwarf and normal.
It is better to add normal_side and normal_below. railway:signal:*:height
