Hello,
What does the yellow light mean? I see that maybe "ZS aus" on some locomotives, but I don't know what does that means. Why it lights when accelerating? And how to turn it off?
I press "H" to turn it off, but it doesn't work every time.

And what do these 3 meters mean? I don't understand what they are so I can't drive it smoothly, which should I focus on?
And could anyone give me a video, I want to watch how experts drive these trains in Zusi.
Thank you.

This control car works with old locomotives that apply power in fixed steps and have no automatic over-current protection. If you try to apply too much power at low speeds the locomotive will disconnect itself from the power supply to avoid damage to the electrical systems, and this yellow light will turn on. When this happens you have to move the power controller to 'Off', wait for the locomotive to change back to the lowest power step, and then you can reconnect the power supply using the 'H' key. Another thing to consider here is that the transition between steps is carried out by a mechanical mechanism, so this takes some time.

The meters show what the electrical system is doing. I don't remember the exact order, I will come back and correct this post later.
One of them is always high and shows the voltage in the overhead wires - you don't need to worry about this because the power supply in Zusi never fails! One of them increases slowly when you increase power - this shows the power step currently selected. Another one will increase a lot when you apply power, and then start to decrease without you doing anything - this shows the current(Amps) being used for traction and if it goes too high the power supply will disconnect.

Learning to drive these old trains with their more primitive traction and braking systems is a skill that takes time and practise to master. By comparison, in today's modern traction you can pretty much just apply full power from standstill and let the computer sort everything out.

Thank you very much!
