Technically speaking on the word "Train" it means a series of connected vehicles that runs along a track carrying cargo and passengers. So yes Maglev's and hyperloops would be considered as "trains" by the formal definition. Thereby meaning that the developers can focus on them as well as Diesel, Electric and Steam trains.

As for the materials they are real world materials. Lithium, Wolfram (also known as Tungsten), Neodymium, Xenon, Bismuth directly found on the periodic table of elements. Aerogel, nanotubes, and borax are compounds that can be made of elements on the periodic table of elements.

So everything that Pixel is doing is completely justified.
