General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

"The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

A "Combined Work" is a work produced by combining or linking an
Application with the Library. The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

1. Exception to Section 3 of the GNU GPL.

You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

2. Conveying Modified Versions.

If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

a) under this License, provided that you make a good faith effort to
ensure that, in the event an Application does not supply the
function or data, the facility still operates, and performs
whatever part of its purpose remains meaningful, or

b) under the GNU GPL, with none of the additional permissions of
this License applicable to that copy.

3. Object Code Incorporating Material from Library Header Files.

The object code form of an Application may incorporate material from
a header file that is part of the Library. You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

a) Give prominent notice with each copy of the object code that the
Library is used in it and that the Library and its use are
covered by this License.

b) Accompany the object code with a copy of the GNU GPL and this license
document.

4. Combined Works.

You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

a) Give prominent notice with each copy of the Combined Work that
the Library is used in it and that the Library and its use are
covered by this License.

b) Accompany the Combined Work with a copy of the GNU GPL and this license
document.

c) For a Combined Work that displays copyright notices during
execution, include the copyright notice for the Library among
these notices, as well as a reference directing the user to the
copies of the GNU GPL and this license document.

d) Do one of the following:

0) Convey the Minimal Corresponding Source under the terms of this
License, and the Corresponding Application Code in a form
suitable for, and under terms that permit, the user to
recombine or relink the Application with a modified version of
the Linked Version to produce a modified Combined Work, in the
manner specified by section 6 of the GNU GPL for conveying
Corresponding Source.

1) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (a) uses at run time
a copy of the Library already present on the user's computer
system, and (b) will operate properly with a modified version
of the Library that is interface-compatible with the Linked
Version.

e) Provide Installation Information, but only if you would otherwise
be required to provide such information under section 6 of the
GNU GPL, and only to the extent that such information is
necessary to install and execute a modified version of the
Combined Work produced by recombining or relinking the
Application with a modified version of the Linked Version. (If
you use option 4d0, the Installation Information must accompany
the Minimal Corresponding Source and Corresponding Application
Code. If you use option 4d1, you must provide the Installation
Information in the manner specified by section 6 of the GNU GPL
for conveying Corresponding Source.)

5. Combined Libraries.

You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

a) Accompany the combined library with a copy of the same work based
on the Library, uncombined with any other library facilities,
conveyed under the terms of this License.

b) Give prominent notice with the combined library that part of it
is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.

6. Revised Versions of the GNU Lesser General Public License.

The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

Long description

It is my attempt to balance the efficiency of fluid transportation using fluid wagons and/or cargo wagons with barrels.
As stated here: viewtopic.php?f=16&t=46845&start=20#p274057
I have a strong feeling that the vanilla fluid wagon is too OP. Graphically, it just doesn't match its insane capacity, which is x3 of a single storage tank. It also makes long fluid train to be rare, since 1 or 2 fluid wagons are already enough.
Therefore, I nerfed it. But that thread also showed that it is necessary to also nerf barrel.

Here are the changes introduced by this mod:

• Fluid wagon:
  • The capacity of fluid wagon is reduced from 75k to 30k (10k for each tank). So now you need longer trains to transport fluid.
  • Due to the above change, the weight of each fluid wagon is reduced from 3000 to 1000, which becomes the same as a cargo wagon.
  • Only 1 storage tank is needed to make a fluid wagon instead of 3. This reduces the total crafting time and raw materials needed from 1.4ks and 243 iron ore to 915s and 153 iron ore respectively. A cargo wagon takes 845s and 140 iron ores.
  • Crafting time is reduced from 1.5s to 0.5s, which becomes the same as cargo wagon.
• Barrel:
  • The capacity of each barrel is reduced from 250 to 100.
  • Stack size is reduced from 10 to 5. As the result, each cargo wagon can now only hold 100x5x40 = 20k fluid.
  (It is intentional to make the max fluid capacity of cargo wagon to be smaller than that of a fluid wagon.)

Optionally, you can turn on "Slow pumping speed" in mod settings to make the pumping speed of pumps slower. As the result, the fluid loading and unloading time on fluid wagons are longer.

Version history

Version 0.0.4 (May 25, 2017):

• Added 2 mod settings for customizing the barrel capacity and barrel stack size.
• The default barrel capacity is decreased from 120 to 100.
• Factorio version is now required to be 0.15.13+.

Version 0.0.3 (May 22, 2017):

• Added a mod setting to decrease pump's pumping speed from 12000/s to 1800/s, making the fluid loading and unloading speed on fluid wagons slower.
  • This is disabled by default.

Version 0.0.2 (May 19, 2017):

• Further decreased the capacity of each barrel from 230 to 120.
• Increased the stack size of barrel from 3 to 5.
• As the result, the total fluid capacity of each cargo wagon is decreased from 27.6k to 24k.

Version 0.0.1 (May 18, 2017):

• The first version.

[Optera]

Probably the only feasible way as the wonky fluid mechanics don't like increasing pipe throughput by 10 times or more.

I would make Barrels hold 120 liters and stack to 5 to have nicer numbers.
That makes 600 fluid/stack and 24k/cargo wagon.

So it is fine to further decrease the capacity of barrels?
Would stack size = 3 and capacity = 200 be a better combination? I guess this will still make robot useful for transporting barrels for short distance.
Just wonder whether it is fine to have only 24k capacity in cargo wagon while fluid wagon can hold 30k.

Tossing up the realism argument one could say the extra space needed for barrels means a wagon holds less

Barrels on belts provides way higher throughput than pipes. A yellow belt has 3 times the throughput of one pipe according to this post.
The only way to combat that is drastically reducing how much fluid is inside each barrel.

For some reason i dislike stacksize 3, how about 5 and 120/barrel?

In my opinion a cargo wagon must have a significantly lower fluid capacity than a fluid wagon,

[Mooncat]

OK. Done!
Released v0.0.2 with even smaller barrels but increased its stack size to 5.

Changelog

• Further decreased the capacity of each barrel from 230 to 120.
• Increased the stack size of barrel from 3 to 5.
• As the result, the total fluid capacity of each cargo wagon is decreased from 27.6k to 24k.

Thought this can be done within a minute since it is just some changes on the numbers.
Opened Factorio to test.
CM was broken again.
Used another hour to fix it.

[leoch]

I like this rebalance, thanks!

Perhaps another thing worth thinking about is pumping speed? Not sure if it's worth changing, but the speed at which a fluid wagon can be emptied is insane.

I have tried lowering the pumping speed, but it doesn't help much unless the speed is ridiculously low.
The original speed is 200 (12000/s), I lowered it to 50 (3000/s) but the loading time is still very similar. The optimized setup (3 pumps connected to 3 separated pipes with 3 different sources) was only slowed down by 0.5 seconds. For the setup that the pumps are connected to the same pipe, the loading time was the same. So it indicates that the bottleneck is on the pipes, not the pumps.
But I won't change the pipes because that will affect many things.

I also tried lowering it to 30 (1800/s), the optimized setup takes 3 more seconds to load. But then it is the same as the not optimized setup, i.e. no room for improvement.
Also, this may also affect the pumping speed on pipes.

One thing to note: although fluid loading and unloading is fast, item loading and unloading can be even faster if you use buffer chests and fully upgraded stack inserters.

Anyway, I will release an update with an option to lower the pumping speed. It will be disabled by default.


Edit: released v0.0.3

Changelog

• Added a mod setting to decrease pump's pumping speed from 12000/s to 1800/s, making the fluid loading and unloading speed on fluid wagons slower.
  • This is disabled by default.

[Optera]

I did some testing of Belt vs Pipe myself.
(assemblers run at 1000% speed though so it might not be that easily achievable without cheat modules)

Barrel capacity 100:
Yellow belts can't keep up with pipe with pumps at both ends.

Red Belts have noticeably more throughput than the pipe constantly draining the right tank.

To get red belt down to this test setups short pipe piece I had to lower barrel capacity down to 60.

A capacity of 40 would put the pipe at the throughput of blue belts. I didn't test this since even two 13.75x speed assemblers can't keep up with that.

Version 0.0.4 has been released.

Changelog

• Added 2 mod settings for customizing the barrel capacity and barrel stack size.
• The default barrel capacity is decreased from 120 to 100.
• Factorio version is now required to be 0.15.13+.

Thanks to Optera for the additional mod settings. Also decreased the barrel capacity to 100.
I think it is the minimum value or otherwise barrels will be really useless.
(And thanks for finding out the shortcoming. )
