TL;DR

Add an "arbitrary item"-symbol that iterates over all items (not only the items in cargo) for train scedules.

Description

Using the new train interrupts, I was able to create the following behavior (similar to the mod LTN):

• by default, the train is waiting at a "Depot" station
• (Interrupt:) If a requesting station of type X (ReqX) and a providing station of the same type X (ProX) are available:
  • Go to ProX and load item X and
  • Go to ReqX and unload item X

This works fine, but you have to define an interrupt for each item: Then I remembered there was some blog post on a generic train item and tried this: Because it did not work, I read FFF-395 again, to find that "Any Item" only iterates over the items in cargo and can not be used for any arbitrary item. Therefore, I suggest adding an "arbitrary item"-symbol that iterates over all items (not only the items in cargo).

(I just found a similar suggestion: Train interrupt station wildcard match.)

I made a minmal example:

I absolutely second this! I would love to see this as a feature!

While there is a quick fix (just connect a constant combinator beside *every* station, and use Signal Parameters Instead, this is annoying, and maybe you want to use the signals for something else...

Thanks for the workaround suggestion.
It works: In my case, you can put a constant combinator to each Depot station with all item signals that should be considered. Using a logistic group (see FFF-382) for the constant combinator allows for later changes.
