[2.0.14] Train with a single scheduled station (that exists multiple times) fails to leave station (even if disabled)

[GulaschLulatsch]

Setting up a train with only a single station (multiple stations with that name exist) in the schedule like this:

The train will drive to the first available station and stay there (so far so good).
Disable/set the train limit to 0 at the trains current station and enable/set limit to 1 at a different station with the same name (In this case triggered by a gate when a player walks close by).

Expected behaviour: If the station where the train is is disabled/train limit set to 0 and a different station (with the same name) is enabled, I would expect the train to go to the available station automatically (once its wait condition is fulfilled)

Observed behaviour: When setting the train to automatic, it will drive to an enabled station once and then stay at the then disabled train station forever.

I also attempted the following:

• Disable/enable stations
• Use "set station limit to 0/1" to enable/disable stations
• Set different conditions to "wait until" at the station

• Have no station/a disabled unrelated station scheduled and add an interrupt (varying conditions) to go to the desired station

• Added the same station twice to the schedule
  • For some reason this led to the wait conditions to alternate between the scheduled stations even though the active station never changed.

  • For conditions that are "always true" this created very fast blinking of the wait condition: (Pulses at a lot faster frame rate than the video was able to capture. Basically every frame)

Attached the savefile with the scheduled train.

I want to build a player "taxi" train around my base, using gates to briefly enable a station and have the train pick the player up

If this is intended behaviour, is there another way I can achieve the desired behaviour that does not involve logistic wires connected everywhere, dozens of PAX stations with unique names or an intermediate "waiting bay" station?

I'll just add that it was always (and should still be) feasible to make normal train schedule that runs same name stations like A -> A -> A ..., and it would drive in a loop as expected. If interrupts do differently then i don't know. Just thought to mention.

If the destination station has the same name as the one where the train is currently standing, then it doesn't really matter what state the stations are in (disabled etc.). The train simply looks at the schedule and says "I'm already here" and doesn't move. That seems perfectly logical to me, so your system is "working as intended".
If you want your train to move to a new location, you must give the new location a different name.

I can confirm, the issue is the same in both posts.

@Saiph: I disagree, if a station is disabled it should not be considered. This was the behaviour in 1.1 and I do not see why this behaviour is better. (I get that the new behaviour of driving to a station even if it gets disabled halfway there is better. However, IF I arrived at my destination AND the station is disabled AND the wait condition is accomplished THEN the train should try to go to the next station that is NOT disabled (if possible).)

• [...]
• Use "set station limit to 0/1" to enable/disable stations

Weird... In my case setting limit to 0 with a combinator caused the train to depart. But I'm planing vanilla. One FFF mentioned that "enable/disable" was supposed to be the same as setting limit to 0 but it seems that the implementation was lost.

In my test disabling a station will indeed not let a train to skip that station in its schedule. It has a blue warning icon for "Destination station full". Actually the target is a free station with train limit 1 (also same thing if limit is inactive), but is disabled.

But i may misunderstand what you mean by depart in regards to this. Nothing happens if you set train limit to 0 for same station that train is already parked on.

[Niedzwiedzislaw]

Maybe screenshot will help. I meant that if I explicitly set station limit to 0 with a circuit, the train leaves the station and goes to the next one as expected. I'm completely ignoring enable/disable because it doesn't help with anything. That's my workaround for now. Unfortunately, it requires a source of electricity, so wires go everywhere a train goes.

I would not expect changing the train limit of a station to have any effect on a train already en route to the station or at it. Take the example of a mine that has the simple condition of "ore > threshold, 1L". If it worked like you want it to the train would leave as soon as it had loaded enough ore to go below the threshold at the station.

Bad idea, please don't implement. Use circuit conditions on your train schedule for this.

You are completely right but on a completely different topic.
The problem here is that a train does not leave a disabled station to visit next one with the same name.

This thread is in the context of a train whose schedule conditions have been met so it is departing Station A, and the next station in the schedule is also Station A. There appear to be some cases where the train will, when departure conditions are met, will leave a disabled Station A and drive to an enabled Station A. In other cases the train will "re-arrive" at the disabled Station A because its old reservation made it still accessible to that train.
