multi-headed locomotives

Hello,
sorry when my Topic is wrong in this part of Forum but I have a Question about multi-headed locomotives.
I've played the old TTD with the TTDX Configurator. In this Configurator was a Setting that allowed multi-headed locomotives with an "top speed increase: 100%"
As Example i have on locomotive with an top Speed of 221 km/h, when i connected this with 3 other locomotives from the same type, i become a top speed of 461 km/h.
I want it now Play the new open ttd also with the same Option but i cannot found this.
Please can me on of you help to solve this?
I use in open ttd following Version: openttd-trunk-r25421-windows-win64
Many thanks advance for you help.

There is no such option in OpenTTD. Multi-headed locs do accelerate faster than the same train with only one loc, and if that single loc is not enough to reach max speed multiple locs will help with that, but the top speed of the loc itself will not change.

Thanks for your answer, but it is possibel to Change this. Also create this Option in Open TTD?
This Setting was very nice and give me personaly many fun.
Without this Setting, I Thinks this slowed the game and the several Train packages (GRF-Files) lose their attractiveness. This is my opinion.

I would guess this is unlikely ever to be implemented
You could use the logic train (search/google it) if you want stupidly high top speeds though

I understand you @ Lord Aro, but it is not possible to create a Setting and everyone can decide that they activate this or not?
In TTD was this Setting also possible.

OpenTTD is not TTD is not TTDPatch. NewGRFs are our choice to modify vehicles. That includes how double-headed engines work. It's up to the NewGRF. Interfering there with a setting would only lead to tears

Yes, in TTDPatch it was possible, but OpenTTD is not TTDPatch
And yes, of course it's *possible* to create a patch/setting to do this, but IMO it's not worth the effort - this is the first request about this I've seen in 3-4 years browsing this forum.
I think it'll come down to this: If you want it, you'll have to make it yourself
EDIT: planetmaker ninja'd me

In TTD it was only possible through a third-party program. Just like you can do it in OpenTTD by editing the source and recompiling it.
The NewGRF trains are balanced by their authors around the way top speeds are handled right now, changing that would horribly break balance.
Also, does a real train get twice as fast if you give it a second locomotive? I don't think so. OpenTTD (and TTD as well) do have some unrealistic parts, but they are inspired by reality.

Sorry,
I don't want to offend. This was only a question/request.
About to Programm this, i have no idea.
Thanks for your answers.
Who knows, maybe some other users want this also?

You did not offend anyone, I think.
But the design decision has been made a long time ago: vehicle properties are modified by NewGRFs. This decision has proven very successful and versatile. And two things (NewGRF and setting) tinkering with the exact same thing is never a good idea.
Also as anyone can make a NewGRF and as making a NewGRF which simply doubles the speed of every multi-headed train is not overly difficult either (provided you play with default vehicles)... that option practically exists, you could
implement it yourself. Even without recompiling OpenTTD.

About to Programm this grf File, i have no idea who can make this.
With wich Programm can be open this grf Files?

OpenTTD can open grf files. But you had a look at the link I provided above?

But only when not using the "realistic" kinematic model, but the TTD original one, IIRC.
In addition, TTDPatch has a "patch var" for this, namely "multihead" (1B) which could be read by newGRFs to disable that probably unwanted feature of multiple engines running faster than single ones.
So, everything was possible, but I doubt the popular train sets ever allowed it (DBXL did not).

Are there any known locomotive sets that contain multihead locomotives?

Actually yes. Even default OpenTTD does.

Interesting, so then how do I create a train with multihead locos in it? I have not found any documentation on how to do this.

You just buy each engine, and then connect them together just like you do the engine and cars.

In the depot, try drag the engines and cars into any order which you like. Unless a NewGRF you use has a different idea of what should be allowed than you, it will just work.

Thanks, dragging the 2nd loco to the existing train is the clue I was missing. It's so obvious now.
