The basic frame that I made for 8-wide train cars.
About this creation
Here is the first frame. It can be used for a variety of train cars, such as the obvious flatcar, a boxcar, a single level passenger coach, and lots of others.
I colored the different pieces to give you an idea of how it was built. There is a 6x8 plate at each end with 8x16 plates making up the rest of the base. Too easy!
Here is the second frame that I created. I have used this design for my Superliner-type passenger coaches. It can also be used for a larger boxcar and for intermodal rail cars.
And once again the different pieces are colored to show how it was put together. Just keep in mind that when using both of these, the plate pieces will have to be connected together. Obviously with LDD, pieces are able to "float" with no problem. Just keep that in mind if you use these! The file is included.

you mentionned how wide, but. not how long, wow, these are long!
They can be modified to fit any length, which is the beauty behind them. This particular length is built to be in scale with my Big Blair steam locomotive. The standard 6-wide car frames from LEGO are nowhere near the size that Big Blair requires, as shown in one of the pictures on her MOC.

Neat! I like the different colors so we can see how it's built.
I figured that even though I added the LDD file, it would be a good idea and be helpful. Both frames are pretty basic, so they should not be that hard to recreate or use, and they are able to be expanded upon very easily.
