lpetrich: does that kLF include contact wire, traveler, and other as well as all pole wire(s) ? Then you have the connections to substations and power lines. Somehow missed it .
That breakdown is not in that progress report. It's likely in some detailed design document somewhere. Some document here:
Electrification Document Library | Caltrain
I'll try to estimate what's what in the wire. The total length of wire is 1.5 million "linear feet" or 284 miles. The route length is about 49 miles, so that means 5.8 wires. But in SF, the route runs through tunnels: (25th St.) 0.16 mi, (Thornton Ave.) 0.45 mi, (Bayshore Blvd.) 0.67 mi, (total) 1.28 mi. Omitting the tunnels gets the ratio up to 5.9 wires. So the route has on average 6 wires along its length.
From top to bottom, the wires are:
- Catenary or messenger wire
- Droppers (vertical)
- Contact wire
That is roughly 3 wires per track, or 6 wires for a double-track route, which is about right.
Route-length estimate from US-101/SR-67 route, from Google Maps.
Is there any figure on what the MAX apeed the CAT is being built for?. Thinking about Ca HSR
I'd have to look in the design documents for that.
