Ummm.... I don't quite understand this one. The first trams arrived over twelve months ago, testing has been underway according to the goldlinkq website, but there is no banner proclaiming opening day (checked today 17/6/2014). Has the whole thing gone belly-up?? Surely it should be ready.... What is it that I do not understand?
That said, it does strike me as odd that a totally grade-separated, brand-new light railway is struggling to meet punctuality targets when it doesn't have to deal with the real-life variable of passengers.
Seems like they're imposing an extremely strict testing regimen that covers not just safety but also punctuality: http://www.goldcoastbulletin.com.au/news/gold-coast/gold-coast-light-rail-services-still-have-no-start-date-despite-months-of-testing/story-fnj94idh-1226959463543
And, well, good on 'em. It's a refreshing change to see a government so keen to do the job properly the first time, rather than half-doing it and having to fix it later.
That said, it does strike me as odd that a totally grade-separated, brand-new light railway is struggling to meet punctuality targets when it doesn't have to deal with the real-life variable of passengers. Makes me think the timetabling standards have been set too high - if they struggle now, what'll happen when you throw passengers into the mix?
Sorry, not a totally grade-separated light railway as shown by the level crossing smashes already recorded.
The problem with "trying to get it right first time" is that when designing and building anything but the ___VERY___ simplest system is that its virtually impossible to think in advance of everything that can go wrong. This makes building such a system VERY expensive. Examples to look at here are most NASA projects up to aprox the Viking space craft. It would be safe to say its nearly always better to build a system from an initial design and then have a decent testing and shake down period, this makes it simple to find the bugs and correct them.
Possibly "segregated" or "on it's own right-of-way" was the way I should have phrased it.
ahhh, now there is a community spirit alive and well!! As I say in most of my logs "thanks for the hide". Can I recommend my "A Lockley Story" earthcache if you are down in a more southern location (Blue Mountains). I doubt you would be disappointed.
Anyway, it seems we wait with bated breath for the light rail to take passengers. Perhaps they should take fare paying passengers before the official opening with the caveat that the system is "still under test" to properly soak it for bugs before declaring "officially open"...
It depends on how much they want to spend.
There are specialist vehicles out there that can be used to rescue or tow a defective tram.
In most cases, however, another tram simply tows the defective tram back to the depot. In Melbourne, there are locations across the network where the defective tram can be 'stashed' for later rescue by the breakdown crew, who rock up in their truck with the tow bar. As many modern trams have the function to couple, it is possible that anyone may be able to do this, however such a function is generally done by the mechanics, as there is usually a requirement to bypass stuff to get the tram moving.
If you page back a few pages on the vicsig 'latest photos' page (http://www.vicsig.net/photos/latestphotos), you can see a couple of Melbourne C2's coupled for towing.
As for how regularly they break down, well, they don't usually break down to a schedule - sometimes you can go weeks without a break down, other times, you have multiple break downs on the same day within minutes of each others. With the size of the GC network, I would be surprised (short of a power surge or something like that) if there was ever more than one tram defective, and I would expect a breakdown rate of one every couple of months once the network has been running for a while, and all the bugs are ironed out.
