The new Siemens S700 trains here are wonderful and will make a game changer for SacRT and save more than spending so much fixing the old trains. This way SacRT can save and use it to expand its light system as its system is lacking not getting you to the other main half areas like one to the Sac. Intl. Airport. and towards Roseville. However, there are two downsides to it. One downside is that the station(s) platform could have been better to rise at all door steps instead of needing the deployable ramps on the two middle doors. Some other transit passenger rails had already stopped using the deployable ramps due to when not working or damaged the cost of fixing it. The second downside is that the new trains' horn blower seems to be way much lower and pretty scary when someone can't hear the horn blowing.
Trams and light rail vehicles are very similar. But the S700 is based on the Siemens Avanto platform that Siemens sells in Europe. They're faster and more spacious than regular trams. In Europe they can travel on regular mainline rail to serve as regional rail. So yes, every similar to a tram, but bigger and more train-like.
