Won’t the overhead wires be an ugly visual intrusion?

No, the wires over the Caltrain line will actually be less intrusive than the hundreds of power, telephone and cable wires over our streets already. Modern rail overhead wiring involves a steel pole every 100 feet or so, with three wires hanging between them. From the side, adjacent to the line, it is scarcely visible. Caltrain’s wires won’t be very much different from the wires which power VTA’s Light Rail line from Mountain View station to Great America.
