This is a picture of one of the trolleys that runs between Lake Oswego, Oregon and Portland, Oregon. This was taken at the south end of the line, which is Lake Oswego.
			The tent above prevents the trolley from getting wet. This is the one story, green trolley. The tracks used to have an overhead line to supply electric power to the trolleys.
		Since the overhead power lines were taken down long ago but the trolley needs electricity to run, it pushes along a little generator on wheels. That's the ugly thing blocking the view of the trolley.
