I've sometimes wondered why modern tramcar makers don't make double deckers.
Yes, modern artics swallow lots of people quickly but they also take up a
lot of space. A double deck artic (with connections at both levels) could
take the same number of people, maybe more, than a single decker in less
length.
I'm guessing there are 2 reasons the main one being that double deckers have
always been a bit of a British oddity.
Partly because normal height clearances on roads (where trams run)
tend to be higher in the UK than other European countries, and most
trams are off-the-shelf European designs.
Berlin does double-decker buses (albeit lower ones than usual for the
UK, if I recall), but they are not common elsewhere in Europe for the
same reason.
Rome has, or at least had last time I was there, double decker buses.
