According to an article from The Telegraph, it seems that Clover Moore is now calling for a tunnel under Devonshire St to prevent the Light Rail from having to go past a few people's houses.
Honestly, if the Light Rail was ever to be built it had to go past someone's house and not all of those people are going to be happy about it. Surely she should have thought about this before spending more than a decade calling for it. Putting it in a tunnel also appears to make it not provide any service for the people it is bypassing which is an interesting outcome.
All this really shows is that Clover Moore is only interested in scoring political points. Time she wasn't listened to at all any more.
