Submitted to the Transit Maps Facebook page by Taylor Gibson. While nowhere near as complex as the New York system featured previously, it’s still an interesting look at a successful rail transit system.

For those unfamiliar with Portland, the thicker lines (Yellow, Green, Blue and Red – shown here as pink for visual clarity, I think) are the MAX light rail, while the thinner aqua and lime green lines are the Portland Streetcar, which has recently expanded to the eastern side of the Willamette River (the top half of this photo).

Eventually, the aqua “Loop” streetcar line will cross back over to the western side of the Willamette at the extreme right of this photo via the new transit-only bridge that is currently being constructed. The bridge will also carry buses, pedestrians, cyclists and the new Orange MAX line.
