Hello from Germany!
Just a short introduction and background: My brother is currently working on his latest model railroad layout that will succeed his Beautiful South Africa layout. I offered to support him with prototype research and some rolling stock and after digging through tons of Youtube videos some questions came up.
In which states is it possible to double stack containers on intermodal cars (I only know about SA for sure)?
Are there states that allow double stacking on well cars but not on skeletal cars?
If you double stack containers on skeletal cars, is it possible to stack two regular height containers or has one to be less tall?
Has the smaller one a specific name? Especially asking about the ones seen in this video with both doors and curtain side.
What's the maximum height for cars? I saw triple stack car carrier cars that would be a real problem to the overhead contact line in Germany, not speaking of tunnels
That's it for now, thanks for all your help.
Firstly, welcome to the Forum.
Double stacking is allowed on the main lines from Perth in Western Australia East to Adelaide in South Australia and as far as Parkes in New South Wales, and from Adelaide North to Darwin. So quite a large proportion of the country is covered. Double stacking does not occur on narrow gauge lines in South Australia or Western Australia.
A new route from Melbourne to Brisbane via Parkes and Toowoomba is being constructed, and it is intended that this will allow double stacking of containers. This would mean the conversion of the line from Melbourne to Illabo (about half way to Sydney) and other lines on the route requiring upgrade.
In Western Australia and South Australia, double stack trains do not travel under overhead catenary, even on dual gauge sections of line. It is expected that the same restrictions would be required in Victoria and Queensland on the new line.
All double stack vehicles must meet a maximum height restriction. the only number I can find is a restriction at Port Augusta of 6.85 metres, which I think applies to the station platform road at Port Augusta station, which has less clearance under the Flinders Terrace Bridge than the main line). EDIT The limit Parkes - BH is 5900mm, which could run through PA station, and the remainder of the system can't be that different...
In Australia,"normal" containers are either 3 metres (9 feet 10 inches) or 9 feet 6 inches high.
As well as the well wagons, there are different heights of skeletal or flat wagons which face different restrictions in NSW and Victoria, and East of Adelaide in South Australia when single stacked.
The RRYY and TRAY wagons had a particularly low deck, and were intended to carry containers with motor vehicles in double stack areas. The upper containers could carry a normal sedan motor car, but were not full height.
The upper containers on double stacked flat cars are often called "half height" containers, although they are not necessarily half the height of a standard container. Some are less than half the height of a normal container, some more.
Some through trains are single stacked, particularly Perth to Sydney trains such as Pacific National trains PS 6 and PS 7 and the reverse SP 3 and SP 5 which are not normally loaded or unloaded en route (although I have seen a single double stack well set on PS 6 which was presumably removed or part unloaded in Parkes.)
