^ those values look like a mix of realistic (steel) with lowered (iron ore) and averaged (plastic) ...

I'm not sure if I like those more or a strict " real / 4 " approach.

Actually I'm fiddling the configs, incl. vanilla. Will be testing soon.
I strictly use 1/4 of real values, lowered to integers.

For some reason (cough) I now suggest to also use a 4x cargo capacity mod - a lot of stuff gets lighter than 1200, but steel ... gets much heavier.
I suggest my mod (not released anywhere officially):
https://www.dropbox.com/s/ztq98kwcywzvoqm/gordondry_passenger_capacity_equals_real_passenger_count_1.zip?dl=1

I've never experienced a big difference in pulling weight of cargo with any vehicle, Maybe it is because all cargo had the same weight. But anyway, I like your suggestion, even if it's for the good feel (I'm sure it will be for more than good feel, though). I will implement your suggestions with the 1/1th scale. Seems fun to see if it really has an impact. Thanks for the suggestion.

For cargo capacity (industry and vehicles), I suggest to use the mods to your personal liking.

I give you my actual numbers here, the contents of my changed files in the mod subfolder res\config\cargo_types\

Thanks, I download your zip. I'll compare the values with what I've found and done already. ;)

The adjusted weights have been intro in Senseless version 1.19. Hope is makes a difference in gameplay (choosing engines for uphill sections). Thanks for the suggestion, GordonDry.

I have to see. Your values make a lot of cargo types much heavier, so a different approach than the "real / 4" approach.

With those values it's not recommended to have a cargo multiplier. (at least before very late games with powerful engines).
If anybody uses my mod I linked above than change line 28 in mod.lua, set to false - or redownload the updated version with different default values.

Passengers still weigh 200 with your mod? Even with luggage that's a lot. But anyway, let it be like that for a while.

btw I like it that you found the way to transportfever.net

You know what? With 4x cargo it's a real challenge ... But then the game difficulty needs to be at least medium, even better is high. Why?
When the train can carry much more cargo, the difference between maintenence cost and income is so much higher with easy setting that you make hundreds of millions with just a few trains.

^this does not have anything to do with your mod, it has to do with cargo x 4 vs. easy game setting.

I've played very short on easy, but it was no fun. If i'm in survival mood, I'll play on hard (and try not to exploit the free maximum resource production system). If I'm in a building mood, I'll play on medium. I did not yet tried the 4x cargo mod, nor the 2x. First I like to experience how it is on 1x.

If you want to test with 4x cargo, you can use my mod as well.

It got 3 setting fields in the mod.lua on lines 27-29 to fiddle.

It defaults to:

local multiplier = 4
-- default multiplier is 4, if you want the vanilla capacity calculation set it to 1. Set it to 2 as recommended value to have more balance of train vs. station platform capacity.

local multiplycargo = true
-- also multiply cargo capacity

local fixloadspeed = true
-- also adjust loadSpeed

As I also use a mod to have more capactity on the station platforms I can use a multiplier of 4.

btw actually I got a building materials train with LNWR DX Goods 0-6-0 with 200 kW and 51 kN on each end (reversible), 25 flatbed wagons, carries 400 units and got a total weight of 1,439 tons. It works like a charm, but needs some time to get to top speed.

Do you know this mod for Tpf1?
https://www.transportfever.net/filebase/index.php?entry/2872

Its main purpose was not to "just" change the cargo capacity or "just" change the cargo weights - it added two new parameters:
maxWeight and maxVolume
So a truck could have a maxWeight of 40 tons but also a maxVolume of let's say 31 m³
So it was only able to carry a low amount of heavy goods like steel but a much higher amount of goods like plastic.

I don't know if the author of that mod plans to port it to Tpf2 - I asked just a minute ago.

But that is also worth a consideration.

Think about a horse cart - with a capacity of 2.
With a 4x mod this is 8 - and steel is a no go. Even if that cart could carry steel.
If the maxVolume of the cart would be taken into account as well as the maxWeight that would be great.

The only "issue" is that it's not easy to make this all happen with generic scripting.
A table with values for all vanilla AND followed by more and more mod vehicles has to be maintained regularly when new mod vehicles come out.

I don't know if a script can measure the volume of a mesh and use this value as a calculation base.
Like for example 60% of the mesh's volume will be the cargo maxVolume if not already set by dedicated patching...

Actually I updated my (yet unreleased) mod to have a simple boolean switch in it to make it somehow compatible to Yeol's Senseless Industries:
It alters the capacities of each good regarding the new weights.

(It's kind of a simple approach to mimic the good old TPF1 mod "Cargo Calculated Weight" - in a very simple way).

@Yeol could you add a global variable to your mod to check for? Something like a boolean YSI_INSTALLED or such?
