This is a Brill streetcar from the early days of streetcars. They were originally built by the J.G. Brill company here in the U.S. from 1900-1915 when they stopped main production. Some were exported to places such as Vietnam, however some were built as "Copies" by countries like Italy. This one looks more like a copy because the windows and roof are slightly different, however the basic shape is the same, 4-wheeled, fixed steps instead of retractable ones as seen on the cars from the 1910s and onwards, and the small "people-catcher" as motormen called them, since they prevent people from getting hit instead of cows. I do see some upgrades, namely the windows, the overhead collection pantograph (originally, they had a trolley pole that had to be turned around when reversing), and a mirror to assist the motorman in the operation of the car. Nice photo! A streetcar is always a neat thing to spot!
he's switching the points, so usually that means he is just getting the car out of the carbarn, otherwize, they would have been changing lanes, which is another reason to have passengers leave, or maybe it just returned from the loop. It is quite common to see empty streetcars if they are doing any equipment moves of the sort.
