My personal interest at this time is for 1-2 trains, but I am not limiting the thread as this thread is targeted to serve all average players not just me.ĮDIT: I am waiving the "input chests must remain balanced", so long as 4 or nearly 4 saturated blue belts per wagon can be sustained regardless of how unbalanced the demand might be. This is an essential element to feed trains to the unload mechanism at a fast enough rate, but it would be best covered in a separate thread to avoid distractions. Train unload management (rails, stop, signals, stacker) - DO NOT INCLUDE. (will likely be the source of throughput drop) (could be some of the 4-saturated-blue-belt designs from referenced thread or something new) As your design will likely be for the specific train configuration you use, give hints if you can (and maybe links) on how to adapt it to a different number of wagons. Post a screenshot of your design, and if possible a blueprint. If you only did partial testing place PARTIAL TEST. If you tested over time with both excess supply (trains waiting to unload) and insufficient supply (station empty waiting for trains), place TESTED next to the throughput number. Post the Throughput as saturated blue belts per wagon. Throughput must be sustainable, not die out due to unbalanced demand (i.e.: what happens when the unload chests become unevenly filled and trains end up blocking the station waiting to unload one last wagon). The designs should be usable and viable for the general population, not just experts. To make such designs available to average players. To identify the highest performing and reliable designs to unload and feed the smelters that deliver to a base's main bus. While interesting, it is not viable for the most common player train unload need, to feed the smelter array that supplies the main bus (since demand on the main bus belts is by definition uneven and can change over time). But it was eventually clarified by the OP that he was only interested in the raw unload step, thus the designs can fail if the demand on the output side isn't perfectly balance ( viewtopic.php?f=194&t=58728). empty train waiting for more than a minute or more than 5 empty trains waiting).A recent thread prompted several interesting designs with the goal to unload 4 saturated blue belts per wagon. You could set up an alarm to tell you when more mines are needed (e.g. And if not then that is a clear sign more mines are needed. Hopefully there always is a mine with enough ore buffered at all times and the next empty train would drive straight to the nearest ready mine. With all trains having an unloading station you can disable stations at mines until they have enough ore buffered to fill a train. trains don't spend time moving between waiting bay and unloading station trains don't waste time in a waiting bay And the time spend moving between the waiting bay and the unloading bay is eliminated. But the time trains are stuck in the waiting bay would be saved. The time for each train would go up, true. But now it would be unloaded from more trains in parallel. Ideally the ore/s unloaded remain the same. So if that is the goal then why have buffer chests at all? I think buffer chests only help when you don't have enough trains because the extra loading/unloading speed lets you get away with less trains. When you reach that point the buffer chests will overflow and the unloading of trains will slow down to the belt speed. You want the waiting stations to be always filled to some degree. ![]() Because if you don't produce enough ore then no amount of buffer chests or train efficiency will prevent the smelters running out of ore. So less time spend waiting for the train to fill at that end.īut from my experience what you want is to have trains arrive faster than the belt can take away ore. This gives the ore mines more time to fill their buffer chests though. Trains will be unloading much slower in my setup. Add to that that you have more trains unloading than the belt can take and the ore will back up. Unloading onto 6 belts take significantly longer. Unloading 1 train into 12 buffer chests per train car takes something around 6 seconds with maxed out stack inserters. ![]() The number of trains that can fit in the station at the same time wouldn't change.Īs for there only being 1 train at the station: That depends on the time it takes to unload and the number of trains you can fill with ore. That's why I suggested changing the waiting bays to unloading stations and not suggested to remove them. Yes, you need to be able to handle all trains being stuck at the unloading station. But if all 5 trains arrive at once, you need somewhere to put them. You can have 5 trains sharing an unload station, and normally only 1 is there at a time (the others are travelling or loading).
