It looks as if it was pictured before any real work was done there.
If the trainees are destined to go out into general engineering industry, big platoons of identical machines aren’t really the way to go. It’s better to introduce them to a variety of typical makes and models they’re likely to meet outside, to get them used to the fact that not all centre lathes, surface grinders and mills are worked the same way. When I learned the centre lathe at a Government Training Centre in 1974, that was the approach they took, so that I’d used quite a range of machines by the time I went into the factories.
