Mr. Slater and Professor Roth, state (in Civil Beat) that $4 billion already has been invested in rail but do not mention what it will cost to terminate and remove existing guideway and facilities (perhaps half that amount?). I concur that staying the course will cost something “north” of $10 billion. Conversion to urban magnetic levitation (maglev), however, can deliver a full project for less than the $6.8 billion in available funding through 2027. A maglev guideway through town (essentially a monorail) would be less physically and visually imposing; alternatively, the trunkline could be routed mauka of downtown with a maglev pod feeder like skyTran for local service. It also would be quiet, and its operations and maintenance will be less than half of that required for steel wheels on steel rails. Maglev 2000 technology can “rescue” rail.
