Hi everyone, I've been wanting to open a discussion on this topic for a long time, well I'm doing it now..

In a nutshell, would it be possible to implement a type of .ENG file that allows the hybrid technology to be reproduced? If so, what changes could be made to the .ENG files to allow the transition between electric and diesel or battery traction?

Many modern trains, especially the latest in Italy, such as the Hitachi Blues, have this technology, and if one day someone reproduces them, it would also be interesting to know how the .ENG files could be programmed!
I left with some photos of the new Hitachi Blues Hybrid Train for Italian Railways:

Hello.
It seems to me, someone did mention this propose a year or two ago, but, as You can see - no development so far.
(so, it's possible to use forum search for recalling that discussion's details, if needed)

I figure this would fall under the umbrella of multi-mode trains. It'll be interesting to see if that is added to the codebase, but it is a pretty niche feature compared to improvements that could help more common propulsion types.

Different eng files or different include files would need to have electric or diesel electric characteristics. What we do not have in OR is the switch that can change from one to the other. There is an extensive discussion about this here http://www.elvastowe...post__p__278325 - if we could only have a switch we could change mode, change voltage collection, change brake characteristics or change final drive gear ratio - see also http://www.elvastowe...post__p__290330

Hello.

The CZ-Sk version already has this. I saw a video of it.
Just as with them, a vehicle can manage several ORTSTractionCharacteristics databases. One for 25kV alternating voltage, one for 3kV direct voltage, and one for electric resistance brake. Of course, the name ORTSTractionCharacteristics is supplemented with a suitable identifier.

The Bernina Bahn has two bi-modal locomotives, the GEM 4/4 801 and 802. However the electric and diesel in OR/MSTS are just two different versions of the loc. The only thing you can change after startup is the sound of the engine: diesel or electric. So just a workaround, no proper solution.

I didn't know this, but it has a different characteristic from the Hybrid traction.

The function you mentioned practically changes the voltage of the train, passing it from 25kv to 3kv, therefore it always remains in the field of electric traction.

In the case of the convoy I mentioned, therefore Hybrid, the type of traction would need to be changed, and this convoy has 3:

1- Collection of direct current from the pantograph

2- Passage from electric traction to Diesel traction

3- Use of the battery module (for short maneuvers or stretches given the autonomy)

therefore, on Open Rails what should be implemented is a function that allows you to have an .ENG structured on the basis of these 3 criteria, physically then from the cockpit, it would be enough to manage everything from the function monitor usually present on the right side of the bench conducted, so in the case of the Hitachi HTR412\312 Hybrids we will have this situation as a monitor, Then, using the "Synoptic" screen commands, the current mode among the 3 mentioned above is managed

Markers are placed on the railway track (Route). After the 25 kV marker, a zero voltage marker follows a few meters away. After an overhead line pole, there is again a zero-voltage marker, and immediately after that, a 3kV single-voltage marker.
The locomotive must be fully decommissioned, then the power type must be changed, and then re-commissioned.
If you mess it up, it will say that the locomotive is damaged. Just like in reality.

Yes, exactly, they are operations that take place during a voltage change.
It happens on some lines here in Italy too, or in border stations between one state and another, or if you switch from a traditional line to a high-speed line

it can be a hig useful function too!

Hello.
I have read posts after previous mine one and have came across conclusion:
Diesel-electric and electric passenger MU have the similar traction motors, but likely different traction characteristics,
Currently, locomotives, defined as "electric" can run in game along unelectrified routes (only warning in Log-file is issued)
Hybrid passenger MUs is not so exotic case nowadays, where electrification is delayed or cancelled.
