Cheaper that way, provided that the infrastructure already accomodates
that approach. Current new designs tend to be double-ended so that the trains
can go in both directions and eliminate the need for wyes or other trackage
needed to turn them around.

We don't have any demostic designs here in the US, or at least I'm not
aware of any. The one we have in Phoenix is Japanes, and it has an annoying
electronic bell. Tucson will open it's revived streetcar system this year:

They have a few antique streetcars from Belgium, Japan, and the US that
they have been running for years on weekends, but they dug up the old trackage
and expanded it to a modern design. They had to dig out one underpass so as to
lower the street to accomodate the taller size of the new train units, and even
so had to replace the pantograph of one of the older cars and replace it with a
trailing arm. It's a very worthwhile investment in city intrastructure.
