The wagon - platform is used for transportation of machines, equipment, long cargo, containers, as well as other cargoes that do not require protection against atmospheric precipitation. The Bulkhead platform has walls on the edges to prevent the displacement of loads.
Four variants of the cargo - pipes, logs, boards and cargo under the awning. There is also a variant without a load.
Three variants of the color of the platform - red BNSF, red NS, yellow TTX
It is possible to combine any combination of cargo and color

Installation:
For simplicity of choice, the archive contains screenshots of the model.

Select the txd file in accordance with the desired color of the platform, red BNSF (bnsf_red), red NS (ns_red) or yellow TTX (ttx_yellow). Then rename the selected file to freiflat.txd.

Select the dff file in accordance with the desired load, empty, pipes, logs, lumber or cargo under tent. Then rename the selected file to freiflat.dff.

To install, please use IMGTool. Open it gta3.img (located in the 'models' folder in the game directory), use the FIND command to find and delete the freiflat.dff and freiflat.txd files and insert the files from this archive with the ADD command.

You can also install this car instead of the standard freebox wagon by first renaming the freiflat.dff and freiflat.txd files to freibox.dff and freibox.txd respectively. By default, the "freibox" car does not appear in the traffic, so that it must be correctly displayed by SA Train Limiter in one of the formats.
