@jvnkyard i'm mostly using push trains so those are really easy to do :neocat_woozy:

ex. turning the station on/off locally, with a circuit to check if there's at least half/whole train.

disabled stations have a train limit of zero now. so a schedule to go to iron ore load and iron ore dump will just go to whoever is signalling they have supply or need it.

i switched some to interrupt schedules where their only order is to wait in a penalty box (depot), but interrupts will either tell them to fill the train with their designated material, or the generic unload interrupt, and its been working alright.

some people have been fiddling with making a generic pull-only network. you can do it, some parts are fiddly. radars are a planet-wide signal now so you can transmit supply and demand to green/red across the planet that way.

last i saw that one can be fiddly because you have to add some wires so stations cancel their own pickup based on incoming trains, since the interrupt can be used to dispatch a train but they don't reserve their station until they actually GO there.

the last problem i saw was that if you don't do anything special, it can end up trying to send all the trains at once. i'm not sure if he was just flubbing the limit, though, since in theory they're supposed to claim the stop so the only way "all my generic trains left at once" is if you had set the limit to like 5 and then all five claimed a slot at once. (which is not... wrong behavior, eh)
