Standard Gauge - 4'8½" / 1438mm - Used in all states/territories (sounds like what you seem to be referring to as 'Narrow Gauge')
QRIG: : First: Don't act smart (you obiously aren't)
Rule 1 of Internet Forums - Making threats via text is just futile, its pure cowardice at work.
Secondly: No, Narrow Gauge is the better gauge in Australia, if all states and territories weren't arguing at the time of choosing a gauge, we would all have Narrow Gauge... Standard Gauge is only more common and a prefered gauge... but if we DID choose narrow gauge in the first place, we would've all been better off, lets face it, aside from HI, who has the biggest trains in AUS?... QR do, Queensland coal trains are not only the longest but also the largest, they have 120 tonne coal hoppers!!! So in conclusion... NO, i am not refering to Narrow Gauge as being 4'8 1/2"... and if you were bothered to read the othe posts before you decided to "spread your (little) knowledge", you would see that the gauge descusion has been dropped because of arguements, so do everyone here a favour and not bring it up again.
Also, this isn't the USset, so don't bother comparing the two countries railways.
You sound exactly like me when I first started in the rail fanning fraternity, ... so don't put on the high and mighty roll with me mate, been there done that ... you don't earn respect this way. You listen and you learn.
The largest coal hoppers used by QR are the 104 tonne VSAS/VSAL and the new 106 tonne VEAL/VEAS. I've seen these trains in action with the electrics and 4000s on the front ... and yes they are formidable, but they look rather average sitting next to the 'Batwing' coal hoppers used on the Hunter Valley system or even the new QHAF/QHBF wagons.
I'm not trying to disuade you from your NARROW GUAGE OWNZORS YUOS ALL stance ... I'm just going to say every system has its pros and cons, NG is limited in how high wagons can go due to centre of gravity considerations (you'll never see double-stack on 3' 6"), it is limited by restrictive rollingstock outlines (if they weren't there, you could see large locomotives and rollingstock running quite safely on 3'6"). However its the merits of QR and not the spacing of the rails that has made Narrow Gauge viable in Australia ... they have over-engineered the network to the max to make sure it performs to world class standards and even creating a few in the process. They have SNX high speed crossovers, a sophisticated train control system (UTC), the ability to run high speed trains safely (up to 170km/h), 99.1% on-time running, the ability to keep themselves self sustained on the transport of export, coking and steaming coal which in turn helps to run the Citytrain network. QR has put input into the modernisation of the Western Australian network, and has leased out the older rail grinder occasionally ... and as previous mentioned the new subsidiary, iQR is now consulting with overseas Narrow Gauge operators to provide modern 3' 6" solutions.
Basically, its not the track spacing that is successful, its the way its implemented and supported.
