I have been semi following a discussion in a group about the building of new trams around the world. We used to build our own in Australia even up to the 1990s. Although the basic design was from overseas I think, it was adapted for Australia and the trams built here. We even built and exported trams to Hong Kong. Even earlier, tram building in Australia was a big industry and employed many people. Now, sadly, we just buy them from Europe.
It would seem from the discussion group, that tram building expertise has been lost in the US and they too look to Europe for design and manufacture.
But wait, England is not Europe. What are they up to with electric street vehicles? How are they going with design and manufacture? Not too well by this picture. Pic is from the BBC and you can read about it there.
