One of the consistent points this blog has made since we launched in March 2008 is that HSR is part of an overall effort to revive passenger rail in California. HSR isn't a substitute for other forms of local rail - in some places, like the Peninsula and Southern California, it enhances local rail by enabling more and faster service on commuter lines such as Caltrain and Metrolink. Prop 1A recognized the need for a linked system by offering about $1 billion for non-HSR passenger rail in the state.
