Notice how simpler the whole electrical wiring is compared to the NEC.
That's really true westpoint. I have been thinking about the reasons why. Here are my thoughts:
1. Caltrain can eliminate the very high voltage, multi-line, very tall power poles over the right of way that are in the old Pennsy territory. I assume this is because old NEC is still captive 25 Hz system with few converters, while Caltrain can run multiple, simple 60 Hz substations frequently along the line.
2. green masts are nice camouflage.
3. general simplification/modernization over 80+ years.
4. two tracks vs. 3~4
I still marvel that modern catenary uses those tensioning weights/pulleys that look so 19th century!
