Yep Västtrafik, the regional operator of western Sweden, runs these kinds of double-articulated Volvos in Gothenburg. I much prefer them to the trams, especially since our politicians can't buy nice trams but only italian Sirio-garbage from AnsaldoBreda.
The oldest trams are five years old and already 30% of the fleet is broken down and out of traffic. The undercarriage rust, they do not work in snow, the airconditioning system is reversed (no heat in winter, no cool in summer), brakes jam, they're uncomfortable, has no suspension and does not work well with sharp turns. Given that the tram network is filled with sharp turns, one might think that this would have been given some thought when designing the tram, but no. The reason is simple, AnsaldoBreda put in a silly offer, several hundred million below any competitor, and the city bought it. The saying "you get what you pay for" has never been more true. And in the end, buying cheap is expensive. While buying quality trams from say Bombardier or Alstom costs more initially, it would have paid off by now. Stockholm bought Bombardier trams and they have not had any problems.
Busses on the other hand work well, they're not as noisy (just a nice diesel clatter), the ride is better (the power delivery is gradual, not ON/OFF as with trams) and they are much more flexible as they don't need tracks. And with Gothenburg being the home of Volvo, it'd be financially sound buy more buses rather than trams, supporting domestic jobs and economy rather than giving money to Silvio Berlusconi (AlsandoBreda is owned by the Italian government).

Before you ask, yes, you can reverse with it too. Only takes a bit of practice.
