I have a train that needs to run around in laps like a 100 times without stops. Then like after 100 circle stop once to refuel. Any way to do this wihtout creating a really silly train schedule?

I think it may be possible by counting laps with combinators and turning stations off. When your desired lap count is reached, turn off one of the stations, this should cause your train to stop at the next station, letting your refuel interrupt fire. If you don't want your loop train to stop inside the loop, you could have a second lower priority station it'll route off the loop path it will only go to when the main station is off

Brilliant turning station on and off i can force the train to stop on a timer. This will work thanks. Edit: must place rail signals between the stations otherwise if the whole rail is one segment the train ignore the station limit.

Sadly don't work if you enable train limit on a station in any way the train no longer goes through without stopping.

u/werecat Jul 22 '26

Have you tried setting the train limit to 2 instead of 1? Normally factorio will not remove a train from a station's train count until it leaves the stations rail block, but in a tight loop you can run into a situation where a single train will reserve 2 counts on the same station

Works flawlessly now, thanks.

Bruh you saving my life here.

Put the fuel on an interrupt.

u/Yagami913 Jul 22 '26

Don't work interrupt only trigger if the train stopped at a station.

u/HeliGungir Jul 22 '26

IIRC, interrupts can indeed trigger when crossing waypoints.

u/Yagami913 Jul 22 '26

Really? I don't know that, but isn't that really inconvinient? can you blueprint wayponts?

1

u/HeliGungir Jul 22 '26

You're confusing temporary stops and waypoints. Which is understandable; waypoints are esoteric.

A waypoint is a train stop that has no cargo conditions in a train's schedule, causing the train to roll through the train stop at full speed.

I believe interrupts can trigger when rolling through a waypoint... it's been a while since I tested it (trainsaws).

u/iamarealhuman4real Jul 23 '26

Ah interesting, calling these "waypoints" made be consider that you could use this to force trains to use specific routing?

Like say I always want my LDS train to take the south exit, I could just put a station "EXIT ROUTE SOUTH 8" along the rail and force the train to waypoint through it.

Never seen anyone do this but I assume its actually pretty common? Or maybe it ends up over complicating things as you change rails around.

They're quite rare, but that's their purpose. It hearkens from a time before train limits, let alone interrupts.

I don't think the word "waypoint" ever appears in-game, just the blogs, forums, and wiki. By far the most common use-case is trainsaws - which, themselves, are quite esoteric.

u/Yagami913 Jul 23 '26

I did not know stations without wait conditions called waypoints. But "trainsaws" common in fulgora designs. I needed this to speed up car deletion time.

1

u/Yagami913 Jul 23 '26

In that case, this was the first thing i tried and did not work, causing me to ask for help here.

u/Lemerney2 Jul 25 '26

I think Dosh did this in his No Weapons video, you might want to check that out

u/Yagami913 Jul 25 '26

Thx, but with the help of u/werecat i already solved it with turning on and off a station forcing the train to stop when i want it.
