The Skoda 15T isn't a derivative of the 14T, it's a completely different
design. The 14T belongs to the same family of fixed-truck trams as the
Citadis etc (though runs better than the Citadis). The 15T is a patent
design of its own and has no direct derivatives as no-one is using Jacobs
bogies nowadays and Skoda has patented the best Jacobs bogie design for a
low-floor tram. So the third stream of design platform in current low-floor
trams - for operators wanting proper swivelling bogie trams - is that
represented by the E class. This has the disadvantage of the bogies being
within the cabins, hence constraining internal layout and door
configuration options, but it's quite a popular design nowadays as trams
are conceived more as standee vehicles and not so much attention is given
to the niceties of seating. Within this design group, however, there are
sometimes different bogie layouts for individual clients, including a
mixture of fixed and swivelling bogies.
So that's the state of the art at present with no major technology shifts
(other than the wireless or autonomous tram) on the horizon. That early era
of experimentation with low-floor engineering, of which the Cobra and
Eurotram were examples, is over.
