Electrification, because it provides powerful acceleration and braking, would decrease travel times. Electrification would allow speeds of 100 mph south of San Jose and nearly as fast north of San Jose.
Electrification also reduces costs.
And that does not take into consideration the increased ridership from faster and more reliable service. Another major benefit is increased reliability that electric engines provide. With fewer moving parts and less wear on the wheels due to more efficient braking, costs and time out of service are reduced both for the engines and the passenger cars. Also there would be reduced air pollution, noise and vibration to business and residents along the route. Thanks to Clem Tillier for the picture at the top of this page.
