It turn out I needed more days to see this city than plan.
Got a chance to ride in the cab of a going from my station to the yard where cars are rebuilt and have a video of the run, but no photos of it.
Wide range of various types of trams, but the high floors are being phased out due to age as well the need to go lowfloor.
They are building a new central station that is schedule to be in full operation by 2014 with a shopping mall, hotels and other buildings. A few of the new platforms were open in Dec 2012 and that will mean the end of the current stub terminal that there now. Once competed, only the west stub terminal will remain as is, since the others ones have become though track stations. All international service will opperate out of the new central station compare using the 4 stations now.
