It expects three mandatory parameters: The points layer, a raster layer (to determine the size and resolution of the output), and a filename for the output layer. You can also provide an optional argument to ...

NaturalEarth has a worldwide railroads layer. It maps the rail lines and has no indication of whether they are used for passenger or cargo travel.

My personal experience is that 99% of the GIS projects I do involve some form of calculation. I can't remember ever having "simply put points on a map", though I'm sure I must have, even if only as a training exercise when learning a new GIS.

Definitely take a look at this: https://rpubs.com/MichalisPavlis/huff_model and the R library hufftools, which also shows exactly how to download and use a street network for an entire country.
