You can see all the options of the headlight, there are no more than what was shown. The test buttons would've also been there...
they didn't USE then though. there are headlight settings on other locos which display "unused" when setting it to them and they don't work in TSW. there's also the hazard lights button in the Vectron's cab but when they used it in the stream it didn't work either
Of all the features the vectron has, the "test cycle" of the headlight is the least of my prefered. With a multi system loco like this i rather would have the different power systems implemented well. Or a simplified engine room etc.
There is no test cycle implemented on the Vectron. It would require like 2-3 new pages with complex logic (especially the debug screen that shows tons of real time data).
I did the physics and a lot of simulation scripting of the loco. chirimu did all the screens (which imo is the best screen simulation in the game so far).
Speaking of the screens. Of all the Vectron footage I have watched. The speedometer infi defaults to the centre screen and not the right as in TSW4. 8 know you can change this. However, the power traction,changeover and brake information is always presented on the right screen. In TSW4 it is presented on the left and cannot be changed to the right screen from what Matt has said. The left screen is generally for Ebula or left off and a tablet displaying ebula info in laying over it. The Vectron set-up as in TSW4 I have never observed before.
The screen setup simulated on the Vectron is prototypical, but to the specific Railpool Vectron variant. It is not a common setup (I don't know of any other operator with this style, but I'd be interested to know). If I understand it correctly it is to do with the safety systems for the countries the RP MS Vectron can run in. They instead installed a fourth screen (top left) for the EBuLa. I'm trying to remember, but I think it's because the real world RP MS Vectron uses Alstom ETCS. The right - center MFD switch is (probably?) not prototypical but a QOL implementation by chirimu since having the speedometer screen (CCD) on the right is so unusual, so for those that want to run with it centered the option is there. Switching the left MFD (TDD) and the center screen or CCD is not prototypical (I'm quite certain of this, but not 100% since Siemens likes to throw curve balls) and not possible in the simulated Vectron.
