But lots of signs are lower... If that were the answer, then wouldn't every sign would be high up?
It probably has to do with the height of the LRV, or the fact that the sign is right behind the other lamp post with lots of lights and so on, at about the same height. The height could have been chosen for sight lines.
I really think the more important thing here is what was the process used to decide to re-invent the wheel by drawing up a unique (ugly/bad) tram icon, instead of using a universally-accepted standard? If everyone did this, signs would loose all meaning. Chaos.
