Hi,

Imagine I have a train stop entity and I want to know if a train is stopped at the station, and if so, I want the LuaTrain.
As of now, starting from the entity I have to do this:

TrainStopEntity.connected_rail
RailEntity.trains_in_block
If it has an amount > 0; search the surface around it to find a loco/cargo/arty/fluid wagon
TrainEntity.train to extract the train
Check if the train is in the station (schedule), or just happen to be stopped (eg. in manual) next to the stop

As bilka mensioned on discord (as he should first look then answer this - his request), the train stop has a function that basicaly goes -> find connected rail -> find train. This could have a nice performance boost to not have to search the surface to get the train that is stopped at a specific station by just TrainStopEntity.stopped_train returning a LuaTrain or nil when no train is stopped.

Kind regards

Though I'd want the station only to give back the train if it is stopped at *that* station, not if it just happens to be "parked" near the station. I.e. "TrainStop.stopped_train" should be nil, whenever the "read stopped train" circuit network signal would be nil.

In the picture i'd expect the left double-station to not report a train.

Yes! I forgot to mension that. I've updated the initial post as well

Okay, added in the next version. It will only work for trains that are currently stopped at that train station, not just "standing there", as requested.
