Box car question
Posted by ndbprr on Saturday, May 28, 2022 12:14 PM

What is the height of the top of the floor above the railhead and subsequent loading dock height?  What is the distance from the side of the car to the side of the loading dock?  Thank you

About 4.5 ft ATR and about 9 ft from the center of track.

If you're speaking of real boxcars, I wouldn't even venture a guess.

For models, though, it might vary quite a bit.  For example, a 40' Athearn Blue Box car (modified with "to-scale" doortracks) measures 10'3" wide, while another similarily modified 50' Athearn car measures 11'3" wide.

A single-sheathed Train Miniature boxcar, with replaced (non-working) door tracks is 10'3" wide, while a similar steel TM car scales-out at about 10'6", and a somewhat modified TM doublesheathed boxcar is also 10'3" wide.

A Walthers 50' single-sheathed boxcar measured 10'6" over the door rollers.

A Proto2000 50' steel boxcar scaled-out at 11'0" over the door rollers, while an Intermountain X-29 boxcar similarily measured 9'9" wide.

I also measured a 40' Branchline steel boxcar at 10'6" over the door rollers.

Finally, in my short test efforts, an Accurail single sheathed boxcar measured 9'3" over the door rollers, and a similar double sheathed boxcar was 9'6" wide, while an Accurail steel-sheathed car came in at 10'6".

Bear in mind that most of these cars had non-working doors, but the ones with working doors did not have the "claws" to keep the bottom of the door in place while it's moved, nor was there a channel atop the doors to keep a moveable door in the door guides.

If you're using cars with working doors utilising claws and oversize door guides, they'll likely scale-out even wider than the ones which I tested.

I would suggest that it's likely not needed to worry about the size of the gap between a loading dock and a boxcar, as most set-ups had a portable (or otherwise moveable) ramp, to allow forklifts, dollies, and workers to move easily from car-to-dock and vice-versa.

Any of my boxcars with working doors do not have "claws" or channels to guide the doors, either at the top or bottom, but instead rely on guides inside the car, as shown below...

Thsi allows for scenes loading or unloading a car, and also for random cars running with a door (or doors) open.

Off Topic Just wanted to say that the box car with the visible bags is really cool!

I find that my boxcar doors are always coming open and there is nothing in them so  it looks rather sad.  I do sometimes think about creating a little project and filling them up with something.  (I don't want to glue the doors shut!)

Hello All,

Check out this thread...Is there a standard or maximum car width?

Hope this helps.

Did the floor hight change when they went from 33" wheels to 36" wheels, or did they have room to adjust for the wheel size?

Wheel size is directly correlated to the design (weight) capacity of the car, so it would be designed with that in mind.

That said, all other things being equal, a 36" wheel instead of a 33" wheel would only raise the axle journal by 1.5", and the difference in spring compression between a loaded and empty car is probably more than that.

No, you just design the car so the floor is the same height.

The NMRA is for clearances and has nothing to do with the height of the floor in the car.   Since all I got for answers to this question was opinions I found a website that goes into detail that the height of the floor is 3'9" to 4'.  Generally lower then the loading dock height to allow downhill loading of the car.

Which means uphill unloading. 

Ideally they should be at the same height.  However track doesn't necessarily stay at the same height and cars vary in height, so it doesn't always work out that way.

I like to do something like that with cars with doors that open. The doors are closed in transit, and I open them when spotting the car.You don't need a lot, just enough on either side of the opening to suggest the car is loaded (or partially unloaded).

Don't forget to check the loco clearence at the dock.   The model might need slightly wider clearance because of handrails and such. To get past the dock to the cars.  An expense oops.
