So in addition to being an interesting railway, this is a really interesting looking locomotive. These locomotives were produced in the early 1980's by Alsthom, and are based on the French SNCF Class BB 7200. Minitrix also does several versions of what appear to be the same shells for the the French versions as well. Contemporary locomotives have gotten much sleeker, which makes the distinctive design of this engine something of standard bearer of 1970's industrial (European) design in my view.
Looking at this Minitrx model, I think the detail is a bit of a mixed bag. While some aspects, like the "Endhoven" heraldry are sharp and crisp, some the yellow paint shows over-spray and is not very sharp. You can see a bit of this above the cab in the below two photos of you look close enough.
Compared to the prototype, there are also a couple of other things that stand out. The grab iron (I think that's its purpose) below the windshield is really thick and is too prominent, and apparantly the wrong color (the Fleischmann version of this locomotive appears to be a little better); the number on the front of the cab is actually a raised rectangular area on the prototype but just a stamped box on this model (perhaps a short-cut compromise from the casting of this for both an NS and SNCF versions?). Finally, the trim around the lights is painted a bright silver, which I cannot see on any prototype photos (it appears to be black on the real thing, although its possible that's just road grime and they come from the shops with these clean silver trimmings which don't last?). To their credit, Minitrix is doing a pretty good job with the color on this locomotive in terms of its opacity. Compared to an older Minitrix model of the Class 1200 that I have, the sharpness of the paint on this version is remarkable (of course, any comparison of any model more than 10 years old in N Scale will probably be the same).
