One of the advantages of running the line along the HWY99 corridor is that's also next to the existing rail which has a lot of at grade crossing. Much of the work is building separated grade crossings for both high speed rail and the freight rail. Another part of the project is electrification of Caltrain. That project is complete and in the final stages of testing with service planning to begin in the fall. That will eliminate pollution and noise from diesel trains and cut the travel time by 25 minutes.
