This is 7-train lighting system
now I will take you to the "journey"
This is a 22-counter (for Local)
and this is a 12-counter (for Express)
This counter can't count because it is not the selected mode.
same as the other two counters on the right side.
Now, let's see my first "huge" sub-circuit
This are the logic block that create the output pattern.
This is the truth table
As you can see, the pattern is a stair-like shape.
I created two blocks because the maximum output of one block can only have 12
and since there are total 22 stations.
Here comes the important part.
I used the same counters as the previous ones
Except, the output pattern in logic blocks become different (you can pause at 0:46 to see the difference)
This is my second "huge" sub-circuit.
(Right in this big big block)
Yeah, I feel it is a kind of over-whelming.
Check out.

Now, let's set the clock and see the function
So, first press is "Go" (means leaving from a station)
second press is "Arriving", (means arriving at a station)
(Because of the time ...)
Now, Changing to Flushing Bound.
(Reset)
Now, changing to the Express mode.
If you have ever took 7 train, you must know these are the stations it stops.
Sometime, there might have constructions in some station stops
I need to improve this part.
and this is the issue that you won't let your passengers know.

That is it. Thank you for watching.
