Altamont Corridor Express runs San Jose Diridon to Stockton. Wouldn't be that hard to model like Livermore to San Jose diridon. entire route is 82 miles end to end. Capitol Corridor trains would be a nice addition as well but their route "San Jose to Sacramento" is a bit longer at 133 miles. if you model Emeryville to San Jose it would be about the same length as the PCS route. thanks for the consideration
