Why do you assume that? The Siemens SIBAS 32 system can be used at home, and an old PC system with Windows 3.11 should be the smallest problem to use at home. The question is, if that's enough to simulate an environment similar to the train.

It's the law in Germany to advertise jobs as open for every sex and there is a third sex in Germany, called 'divers' (means: other)
English has "gendered" words in rare, exceptional cases (master/mistress?) but for Latin-based languages it is the opposite.
German can be weird in that the grammatical gender of a word doesn't always match the sex or gender of the person it describes. The most famous example is probably that das Mädchen (the girl) is grammatically neuter but unambiguously describes a female person. Nouns describing professions, however usually (always?) have a masculine and a feminine form and do describe the sex or gender of the person. An ad hiring a Fahrer would have the same meaning as "male driver" in English. That would be illegal sex discrimination in the USA or Germany.
The linked ad also included the following text, which has no connection to reality for the English translation:
> Note: In order to improve the readability of the text, the masculine form is used to refer to persons, functions, etc. However, it stands for all genders without exception.
