Submarine

Interesting, I would have thought that they would preheat the hot metal car somewhat to keep the metal liquid longer.

Is that a steel 3 mounted on the top? Looks like a spray painted 3 on the right.

Binky,
They do preheat the inside of the cars with a gas torch before filling, not only to help keep the tep of the steel where it needs to be, but to avoid damaging the car. These cars are lined with fire brick, similar to whats inside a furnace, or a locomotive firebox. The bricks prevent the molten metal from burning through the sides of the car, but if they just dumped 2900 degree molten steel in the car the bricks would shatter from the thermal shock. And satiria, yes, that is a spray painted number three. These cars don't require all of the regular data on other railroad cars, since they don't ever leave the steel mill property and never enter interchange service.
I am a model railroader and I am building a model of a steel mill, and as a result, I have done all sorts of research into steel mill rail operations and its related equipment.

And we thank you for sharing that knowledge Ian. :) Loving the history, knowing what we are seeing is used for and how it works.

Thanks Ian for the great information!

I wouldnt want to get into a fender bender with this thing.

Thanks Ian, You should post pictures of your completed model when ready.

It almost looks as a old time cement mixer.

Another great video and photo. Thanks Mr. Motts.

Ian, you are super awesome!!!

My kids (and me) are LOVING these videos along with the usual amazing photography!

Thanks Ian, I would also like to see picks of your railroad when it get done.

Again, wonderful.

Ian,

do you have brochures or specs for any of these submarines? do you know where I can find some?
