Rolling on hidden wheels

Rolling on hidden wheels - A 9000-series Socimi tram of Rome’s public transportation company ATAC runs towards the terminus Termini. These are articulated trams, but it seems as if they don’t have wheels in the middle. Of course, they do, but they are relatively small, located underneath the narrow, box-shaped central section that also serves as a passageway between the tram's two largest parts. The trams were built in 1990, so they’re not exactly new, but not yet classics either, which is why the term 'youngtimer' fits them well.
