So I've been paying closer attention to the light panel behind the engineer's seat (above the fuse panel), and I think I have most of the lights figured out, why they might be on in certain conditions, etc., except the one labeled "E Brake", which seems to always be illuminated. What does this light indicate, and is it realistic that it would stay illuminated during normal operation? I know not all the indicators are simulated perfectly, so was just curious about this one.
