- Well, this gets into the "Argument" about what is the corridor. The
- thru route, DC-Boston USED to be 11KV/25Hz DC-NH, albeit on two
- different RRs. A portion of the ex NHRR is now 60Hz commercial power
- (roughly Woodlawn-NH, tho they are extending third rail partially,
- so Woodlan is no longer right.)

- The generating equipment, while on power compnay property, is "owned" by
- the RR (I expect AMTRAK picked up ownership when the bought the
- corridor). The transmission lines are largely on RR proerty, and, i
- suspect all RR owned and maintained. The rate paid the power companies
- is low, but i doubt the power companies are loosing money. (same
- applies to the large rotary frequency convertors that are also part of
- the system.)

- hmmmm I know that between Bridgeport and NH, the local power company
- rents tower space and runs 100odd kv transmission circuits on the rr
- catenary supports. This dates to the 30's. The wiring has nothing to
- do with the RR, it was just a hand place to run the wires. I don't know
- if the DC area lines are the same, or if there is a 25 Hz feed there.

- I don't think there was ever any 1500Vdc on the corridor, proper.
- Lackawanna used to have some commuter service at 3KVDC in NJ, which
- terminated in Hoboken. This was converted to 25KVAC/60Hz about ten
- years back. There was not an electrifed connection to the NEC proper,
- tho that has been proposed over the years.
