feature request: per-station signals for inactivity/finish-loading.

[ManicMiner]

There are global settings which determine if trains should finish unloading at the requester station, and I like this option for most stations.
However; for other stations (like the pollution filters for K2+SE), I want to have an inactivity timeout and only load the amount requested.

• It appears implementable by adding new station signals which override global defaults.

I stared adding a "delivery chain length" signal which would hint the dispatcher to schedule stops at up to X requester stations, but wonder if there is a way to achieve this with LTN as it is.

Enable "Schedule circuit conditions" and build whatever logic you want for keeping trains locked in a station or force them out.

Thank you -- this suggestion works, but ...
- I have 190 stations and did not want to re-wire them of all (just the ~15 pollution filter stations).
- The default setup was so nice, that I had previously removed all circuit connections to my train stops.
- The short circuit global requires a "send to train" circuit connection for each LTN station.

Instead, I implemented a per-station "use circuit conditions" control signal.
- This selectively enables short circuit scheduling (e.g. only for LTM stations with the control signal set).
- I didn't see a reason to enable it for depots, but that could be done as well.

If you think this is worth including, I would be happy to transfer ownership to you (in retrospect, the code changes were not complex).

I need this!

I'm running LTN on K2SE and have many large stations for mass-produced items... but then I have one station that provides 'stuff' - things I just need 1 or 2 of for orbit. The train gets full instantly, but because it is scheduled to pick up tons of different things but is full, it just sits there fro 120 seconds.

I need to set ONLY this one station to send trains away as soon as they're full, or are inactive

Enabling circuit conditions globally has no effect on stations that don't make use of them.

The only requirement is for a single wire to connect to every station, can be just an isolated pole with a wire between it and station.
Otherwise trains will try to read from a not existing circuit network and wait forever.
