@@thecarwasherofshangri-la Two locomotives in the back would allow for even more wagons I think since both locomotives can be in the curved part and you do not need a curve in the other ends since it can be a terminal :)
Thanks man, fun video Artillery trains have an air resistance of 0.015, compared to wagon's 0.01 and loco's 0.0075 So if loco-first have 100% drag, wagon-first have 133% drag and arty-first have 200% drag. Probably why artillery was so shitty. As for energy efficiency, I'm wondering if we aren't in a flamethrower scenario. The one where even the worst, almost-empty oil patch can power your entire train fleet no problem.
I think the energy efficiency concern is less about the materials, and more about lag/logistical overhead. Unless you're using wood/coal, you probably can make way more than you need and making less is better because you can do other things with your CPU, rather than because it's easier.
The only application where "locomotives not in front" is a no-brainer is trains with more than 1 locomotive. Putting the extra locomotives in the back has literally no downsides. You still get the drag bonus from the locomotive in the front, the station is next to that locomotive and doesn't block inserter positions, and your station platforms fit in the same footprint as if you used 1 locomotive. Well, actually, there is 1 downside; You don't get the increased breaking force.
@@Michaelonyoutub True, fuel logistics is ever so slightly more involved and can in rare instances be an actual problem. But I'd guess that most players switch to drones for fuel at some point. And in most cases where you are using belts, you usually run them to the next set of train stations too, so you're passing the back ends of the trains anyways. The only exception that I've seen is a city block scheme where the fuel comes in on its own train. So if you really don't have the space for one extra fuel belt, then your station layout has to be weirdly hyper-optimized.
@@roderik1990 True, better acceleration from _less_ drag and better braking from _more_ drag are very very very close, to the point where I would say you can assume they cancel exactly.

The algorithm recommended this video to me and I love it. You’re thorough, have a great voice and are exploring something fun while not making the video longer than necessary. Subscribed.
Great testing! I am a fan of a 1-8-(-1) train where the tail pushes. This gives a slightly shorter requirement on the straight as you mentioned and has the subjective bonus of having smoke from both ends of a moving train.
Since you can get legendary rocket fuel really easy by just duping it on aquilo, I would like to see a test using legendary rocket/nuclear fuel, they give a really great acceleration boost, maybe the "realistic" scenario has the reverse pull out ahead stronger, since they are more equalized with the normal in acceleration, so the faster stopping matters more
I love how this gaming community has a game with just about limitless land to build but they will obsess about getting just a few pixels of space out of a design
i tried and failed to make reverse trains work in a death world i was doing about a year ago. This is going to make me consider using them for a space age run with friends, that plus the goofiness factor with running them makes me like them a lot. Very good and informative video!
One potential advantage to wagon-first trains is simplicity in expanding logistics. I'm currently working on a set of blueprints that features factories that are served from a single wagon section of a train, tileable so you can place as many factories as you have wagons. You can have multiple trains in parallel if multiple resource types are required, and you can have a factory for each wagon on the train, each serviced by its own wagon of materials. The advantage of this particular layout is that if you need to increase production, just slap down more factories along the ones you already made, lengthen your trains, and maybe modify your mining bases to accommodate for the length of your new trains. But, as you've pointed out in your video, the train station does remove a lot of potential unloading zones on one side, and when I experimented with this train layout when prototyping my blueprints, I found this caused a lot of issues with my factory layouts, too.
There's multiple options, I default to the mod "Blueprint Sandboxes" though it's only one option of many. It's not the one this video uses I'm sure, but it still serves the same purpose.
In the "Surfaces" tab of the editor, there should be a few buttons to fill the map with lab tiles and clear any entities/decoratives. Should yield a map similar to this.
In my vanila playtrough, I had a 64 wagon train for coal. It was 32 wagons in front, then 8 locomotives and then 32 wagons behind. The loading station was U shaped and those locomotives fit in the bend.
It would be interesting to see how the performance difference is affected by congested networks and as the typical block size tends towards the length of trains. My gut is that, as ability to stop becomes the limiting factor for train speed and keeping blocks unreserved, this will further favour the wagon-first design
So, legendary nuclear fuel (and possibly legendary rocket fuel as well) might actually be *faster* with reverse trains, since they can (probably) accelerate faster than decelerate. So, additional air resistance will decrease the time it takes to break more than it will increase the time to accelerate.
I did this to make a tiling design with 1-4 stations slightly narrower, giving better roboport and pylon efficiency. Didn't think about the air resistance but I don't think fuel efficiency really changes my mind
Very cool video. Thanks for the science! Does atmospheric drag change based on the planet? I could definitely see this setup being used on Fulgora where fuel efficiency is unimportant and compact load/unloading stations are a must.
To follow up pm your closing thoughts, of compact builds is the goal a more practical answer to recommend would be bidirectional trains, as their stops are entirely vertical rather than horizontal and can fit in series as little as 4 tiles apart
Does the drag modifier apply to backwards locomotives? Because that would open up _the_ most cursed trains: double headers, but with the locomotives pointing inwards towards the wagons.
So, reverse trains are slightly worse in through-put and fuel efficiency. But they are slightly better in terms of space and station shape flexability.
imo the freight cars look more aerodynamic than the locomotives lol Also, iirc streamlining isn’t really effective until speeds somewhere past 100 mph (for example, look at the UP FEF-3s that were designed to operate up to 120 mph, though it isn’t known if they ever did get up to that speed), though idk how fast Factorio trains are.
Nice!! I use 2-8 trains ans it bothers me to make 2-8 trains because ot not in the middle of a block, so i wonder is it better to make 1-8-1 trains? Visually all wagons would be exactly in the middle of a block to make nice simmetrical load/unload stations. And then i get to this video! What do you think about 1-8-1 trains?
not only the locomotive is on the back "pushing" the wagons, but he even have 3 wagon trains, good luck balancing the output, what do you use? a 4 to 4 balancer and just feed it with 3 belts? or no balancing at all? that could be even more cursed
My strange city block design has an evil flaw where I need to deviate from the pattern to build fluid wagon unloading. Essentially no reasonable station could draw from all 4 fluid cargo wagons, it was always exactly 1 tile off. Having learned about reverse trains, I can now fix this irregularity. But do I really want to?
