Solved: Tanker Truck and Rail Car Correct Models

Anonymous · ‎07-13-2018

I am doing a research project about loading/unloading on Tanker Trucks and Rail Cars. Does anyone have models that are dimensioned correctly for the United States? I am mainly talking about the location of the loading and unloading ports for the trucks and rail cars. If anyone has such models they would be greatly appreciated or if anyone could direct me to where I could find some.

Thank you in advance.

What kind of railcars? Gondola, flat or box?

There are many different types and sizes of rail cars and tanker trucks. What specifically are you interested in?

My experience retrofitting rail cars is that each manufacturer and initial purchaser makes slight changes in car geometry. About the only thing that is consistent is the coupler height, truck size, and overall width to meet specific Interchange requirements. The American Association of Railroads has several books on design requirements that may be helpful.

I expect that there are Federal DOT regulations on the tanker trucks, but I doubt that there is a common interface standard among manufacturers.

You may have better luck contacting specific manufacturers and asking for drawings/models.

Don't know much about the tanker trucks, but a little about the railcars. Depending on the type will speak to the load.

What has already been mentioned regarding specs, AAR has some specs online.

Checkout these links.

- Petroleum Trailer Tank . 4 or 5 compartments. Bottom (central right side) loading. US DOT 406

- Diesel Trailer Tank. 4 or 5 compartments. Top loading

- General purpose chemical trailer tank (not insulated "lagged") Single compartment top loading

- General purpose chemical trailer tank (not insulated "lagged") Single compartment bottom (rear) loading

- General purpose chemical trailer tank (lagged) Single compartment top loading

- General purpose chemical trailer tank (lagged) Single compartment bottom (rear) loading

- LPG trailer tank. Single compartment, bottom loading central mid

- Cryogenic trailer tank. Single compartment, bottom rear connections

- Dry Bulk (powder) trailer tank, top loading, single manhole

- Dry Bulk (powder) trailer tank, top loading, double manhole

Rigid 4x4 wheelers and 4x6 wheelers

- Fuel Oil Tanker, 4-5 compartment, bottom loading

- Fuel Oil Tanker, 4-5 compartment, top loading

If anyone has models of this, it would be greatly appreciated. I need accurate models depicting where the loading and unloading ports are at.

+1 for the comments already offered : I'm not aware that there's a 'National Standard' for either rail or trailer.

I haven't done a *ton*, but in 6 or 8 rail loading facilities, and maybe 20 truck loading facilities, there's a lot of variation. Manufacturers may offer some standard designs, but my understanding is that they're most often customized to meet specific material needs - flow/viscosity/abrasion/wear/material compatability/etc. There are so many variations, I'm not sure it would be practical to have national standards.

I may be wrong - not a logistics expert, just a process plant guy 🙂

Scott,

I reached out and found the exact kinds of rail cars and tanker trucks they were asking about.
