We’re headed out to the West Coast this morning on Streetsblog Network, where we are now featuring feeds from 142 blogs and adding new members all the time (welcome Kansas! welcome Kentucky!).

A Lesson from San Francisco: How Streetcars Can Evolve. Seattle, WA: Can streetcars that share space with car traffic become part of a true rapid-transit system? From Seattle Transit Blog, a historical analysis of the way streetcars in San Francisco have done just that.

Un-Malling 14th Street. St. Louis, MO: When is a pedestrian mall not a good idea? In 1977, the city of St. Louis closed a shopping street downtown to cars. The experiment failed and the street went dead. Urban Review STL looks forward to the restoration of the street grid.

Plus: Electric trains in California, more on the Big Bad Big Box and a fun video about walking.
