    I seem to recall this being mentioned that the train was able to redistribute traction by lifting a wheel. I had a couple of questions if I may.

    • is that right?
      When does this happen?
    • What happens?
    • How do we know it’s happening?
    • What loco does it happen on? Front, all?
    • Anything we can see on mfu when it happens?
    • Anyone have any pics in game of it happening?

    I'm curious about some of this as well. I know it has to do with these two cylinders connected to this bracket.

    When this feature kicks in the bracket twists to some degree, I think they showed it in action in one of the streams.

    Aside from visually looking at it, do we get some kind of notification somewhere?

    It happens when you get a bit of wheel slip. The animation occurs and the red squiggles appear in the HUD. That’s all I’ve observed.

    It doesn't lift a wheel as such, but instead it shifts its weight. It will reduce the weight over the middle axle, and applies more onto the other two. Because trains get more grip when more weight is applied onto the wheels, the two outer axles get more grip, helping during wheel slip.

    It is correct, and it happens inside the bogie assembly by moving cylinders, so apart from those rotating things in the picture above, we see nothing. I do not have the game so cannot help in any other regard.

    To recreate, set up the camera to have the bogie assembly in view. apply the automatic brakes, bail off the independent brake, and apply enough power to wheel slip (shouldn't need to go into cab view to do this, could be wrong). When you do slip, observe the rotation of that bracket, then stop the wheel slip and observe again the rotation of the bracket. Repeat as necessary.

    The ES44C4, despite being a 6-axle loco, only has 4 powered axles - the centre axle for each bogey is unpowered, so is only used for weight distribution (so it's an A1A-A1A rather than C-C or CoCo). In times of wheel slip, the cylinders on the side of the bogey will actuate, which slightly lifts the centre axle (it never comes off the rail completely) and re-distributes the weight to the front and rear axles, increasing their normal force and therefore their traction.
