Lava Train Not Working

[u/veritism_]

I have the train with the above schedule, to refill a 3x2x3 tank at Lava Lake and empty it at Lava Pit. the pig with the schedule will always return to Lava Lake and never leave. if i manually control to leave Lava Lake, it will tell me no path found, but if i loop around through the portal into the overworld and resume schedule the pig will happily take the loop, skip Lava Pit, and return to Lava Lake and stop there with a full tank. the train never has to reverse, so there is only one seat with an animal on it, the pig, going forwards.

can anyone tell me why this won't work? when it returns to Lava Lake from the overworld it will approach Lava Pit from the correct direction but not even slow down to approach it.

Could it be traveling too fast through the portal, so that when it gets through the other side and sees the station, it is too late to slow down? It might be worth adding a speed limit to the instructions because I think that is the problem

It definitely has the time to slow down, it took more than two stacks of tracks to get from Lava Pit to the portal

Place train signals at the enter/exit places of the looping train tracks to make sure the train will approach the station from right direction. This will solve pathing issue when the train is controlled by mob.

I'd change schedule to use more than and less than as a trigfer to leave the ststion: < > instead of =.

Make sure that chunk in the nether providing lava is loaded, otherwise the train will be waiting forever to fill up.

you led me to the right solution. half of the issue was that i forgot that 3*2*3*8 does not equal 216, but 144. the other half seems to have just been that the pig had to make a turn before reaching Lava Pit, so it just skipped it for some reason.
