Thanks chaps. I can't take credit for the construction I'm afraid - this was printed some time ago by a company that sadly stopped producing the rolling stock. I have a gunpowder van by them too - I'll take some pictures and post them in case they're of interest.
Andrew - They were printed with a Prusa i3 Mk3s and a Creality CR-10S Pro v2
I'm currently test-printing my own 16 Ton Mineral Wagon. I'll get some pictures of that up as well. That is being printed on a Creality Ender 3 Pro
I'm just looking at the Creality Ender 3 V2: I had no idea these bits of kit had crept down into my price range. I need to check I can make it work with my Chromebook before splashing any money, I don't need a PC for anything else so I don't want to add that to the cost.

Yes, the cot of the technology has dropped a fair bit and the quality has improved too. The end result is affordable printers that can achieve decent results that once would have been the preserve of kit that cost more than twice as much.
In terms of getting the print to the printer, the choice is usually to have it hooked up to a laptop/chromebook/some such, or to copy the stl file onto a micro-SD card which can then be placed in the printer (they come with micro-sd card readers built in. I tend to use a laptop, mainly because it gives me much more control over how I want the printer to print, using free print software (I use a product called Cura). It also negates the need to airgap the files between the two every time.
From what I can see, it's definitely possible to run Cura on a Chromebook. I agree, you certainly wouldn't want to invest in a laptop or something just to be able to 3D print
