Improvements to rail networks

Trains running on the rail network should be able to stop at fuel stations during missions—that is, change their route as needed to refuel. Currently, trains, after loading cargo at one station, continue to their final destination, ignoring fuel shortages. This sometimes results in trains running out of fuel en route to their destination or, afterward, on their way to a fuel station.
In the station settings (for regular routes), there's a setting called "Allow only trains with the appropriate fuel type." I believe this setting should also be extended to the rail network.

I also forgot to add that it is worth introducing permission settings for the transportation of specific cargo by the network.

Seems like a poor network build.
My trains fill up when they load because I put fuel at the stop.

Unfortunately, I had to do the same. Ideally, I would have liked the opposite—to avoid refueling at stations, and instead to do it at specialized points along the main route.
