But, at that stage, the Australian states were, in effect, countries in their own right ... and growing children aren't noted for listening to Mother. That's where the Irishman came in, one F.W Shields, a railway engineer employed by the Government of New South Wales. He advised, probably correctly, that the 5'3" gauge, as used in Ireland, would be more serviceable for the loads and distances involved.

The Governments of South Australia and Victoria agreed, and followed suit by planning their railways to the 'Irish' gauge. However, Shields was replaced by a Scotsman named Wallace, and, following his advice, New South Wales adopted the 4'8 " gauge. The other two States, feeling that their plans were too advanced to change, retained the 5'3" gauge.

Meanwhile, South Australia was also building a network of 3'6" gauge 'country railways', intended mainly for carrying farm produce and other freight. The narrow gauge was chosen as being inexpensive to construct and to operate, thus keeping freight costs down ... passengers were carried, but their comfort wasn't really a high priority.

When the Australian States joined in 1901, to form the Commonwealth of Australia, Western Australia demanded a rail link with the other States as a condition of joining. Thus was born Commonwealth Railways, operating from Sydney to Perth on the New South Wales standard gauge metals ... giving South Australia separate systems in three gauges!

It's a complicated story, and, in summarising it here, I may well have sacrificed a little accuracy in the interests of conciseness. The place to find the whole story, graphically illustrated, is at the National Railway Museum, in Port Adelaide. The Museum is in Lipson Street, on the site of the former Port Dock Railway Station, to where it relocated from Mile End in 1988.

Locomotives and rolling stock from bygone days are displayed in three undercover locations. In the Goods Shed, a mainly volunteer work-force carries out restoration work on exhibits; the Main Pavilion incorporates a Break of Gauge platform, as well as several side exhibitions, such as Women in the Railways, Operations and Signals and Railway Development. Around all runs a 457mm (18 inch) gauge miniature railway, which is steam-hauled at week-ends and holiday times.

The Commonwealth Railway Museum is in a separate shed, and part of its display is devoted to the legendary Ghan railway. This was a 3'6" gauge steam-hauled line, built in 1929, originally intended to carry passengers from Adelaide to Darwin but which, in fact, terminated at Alice Springs, almost in the centre of the country.

The train took its strange name from the 'Afghan' (actually Pakistani) camel-drivers who pioneered the route. The two-day ride to 'Alice' in the wooden carriages, which usually had an open platform at each end, was always regarded as something of an adventure. The intense heat, flash flooding and termites eating the wooden sleepers (cross-ties) often delayed trains, sometimes for several days. By 1982, the track had deteriorated so badly that the trains, by now diesel-hauled, were discontinued. The track was abandoned, apart from the stretch between Port Augusta and Quorn, in the Flinders Ranges. This section has been restored, and operates as a tourist attraction by the Pichi Richi Railway company, to give a flavour of what rail travel was like in 'the good old days'.

But, that was by no means the end of the Ghan. Alice Springs is now served by a twice-weekly service over a standard-gauge track laid to the west of the old line. The New Ghan offers sleeper accommodation in two classes, 'Gold Kangaroo' and 'Red Kangaroo', as well as 'sit-up' accommodation for those on a budget.

The train also incorporates car transporters, so that passengers can take their cars with them; in the old narrow-gauge days, these, with any heavy baggage, would be brought on a second train called the Chaser, which followed some time later.

And, since 1st February, 2004, Alice Springs is no longer the end of the line. It's been continued northward to the northern port of Darwin, which was, up to now, isolated by rail from the rest of Australia. The new line offers the opportunity for passengers to take sight-seeing side trips at Katherine and Alice Springs; these will be free to Gold Kangaroo passengers, and available at extra cost to those in Red Kangaroo.

I was recently lucky enough to visit Adelaide's Keswick Rail Terminal, and be shown over the Ghan, which was being readied for departure. The station carried an air of excited anticipation, even among the staff, as the train prepared to leave on one of the world's great rail journeys - which, with the new extension to Darwin in service, promises to become even greater!
