Nice work Alwin.

I wonder why they fabricated the body so short compared to the wheelbase ?.

Thanks guys.

Michael, the iron ore these cars transported was so heavy that if the cars were made bigger the maximum axle load were exceeded.

My model is not 100% correct. On the real cars there are even more reinforcements of the body. Because of the scale (H0) and to keep thing workable I have some omitted.

Thanks Alwin, the weight of iron makes sense c/f the wheelbase.
Considering it is HO scale you've done a good job !

Holy cow!

How'd I miss this thread? Alwin, that's a great looking car. All you need now is about another 100 more and you can have your own ore dock!:bg:

And to Michael,

Yes, iron ore is very dense. I was allowed to pick up a chunk of the ore while in Hibbing, MN at their mining museum and it's heavier than most other types of rock. While coal weighs about 1100 kg per cubic meter (more or less, depending on type of coal), and copper ore weighs about 2000 kg per cubic meter, iron ore can weigh as much as 2900 kg per cubic meter, nearly three times as much as coal.

That's coming from a UK source:

http://www.simetric.co.uk/si_materials.htm

In addition, I believe these ore cars were designed to carry ore pellets, which would be even denser than the ore straight from the mine since the pellets would be filtered and condensed iron ore. That's why an Iron ore car and a coal car, both rated to 100 tons, are completely different sizes.

**EDIT** I see Alwin already answered the question, but here's the science behind the matter.

Thanks guys.

Have done a little more. Made some parts of the door operating mechanism. Many little parts of that are missing but are not very visible and to smal so I leave them omitted.
Also made one grab ladder. Are there on both side ladders or only on the side were the brake wheel is?





Underside with the parts of the operating mechanism.

Alwin,

I like the look of the car, it gives off the impression that it has been in service for a while. Post more photos please!

Thanks James. The looks of the car is because that's the best the "factory" could build.


I have modified the trucks because the couplers where way to far on the outside. Normaly this kind of car ride almost flange to flange.

Original one on the right, modified one on the left:


Other view angle:


Two modified trucks coupled:

Outstanding built! It's probably made better than the real deal!
