New Train Oilcar Image

I made this image as an experiment for making images for teaching. I copied it from my son’s drawing of a train car, which he in turn copied from Richard Scary.

I found it relatively easy to make this image in inkscape, but I am still learning so it took a while. Perhaps 25 or 35 minutes. I definitely looks promising for making more royalty free images that I can use without worrying about copyrights.
