Grade separated rail works so much better than buses and streetcars for longer distances:

• It doesn't get bogged down by all of the overwhelming personal vehicle traffic. It doesn't even need to wait for traffic lights!
• It can carry far more people per vehicle than buses ever can for physics and safety reasons.
• You can depend on it to be consistent both temporally and spatially, barring maintenance events.

This is top of mind because my wife and I have been doing stuff in Capitol Hill a lot lately and getting from North Seattle to there is far better by light rail than it has even been by bus.
