Why does the orange line on the front curve upward? If it's supposed to
represent a safe distance from zap, shouldn't it curve downward if anything?

The line has to be visible by anyone standing at rail level. If the top of the curve at the front of the train is the highest safe level, and if that level was continued round to the side, it would be on the roof and probably not visible from rail level, hence the lower level at the sides. Some other stocks have an upward curve at the front, e.g. class 700, 158, 159.
