- Unless I'm mistaken, the entire NEC uses 11kv AC 25Hz. This, of course, is
- a pain to the local power utilities because they have to maintain 25Hz
- generating and transmission equipment. If you ride the WashDC Metro red
- line, you can follow the power lines from the NEC mainline into PEPCO's
- Benning Road Station (oil fired boilers?). As far as I know, there is a
- little 60Hz used for traction, and no other AC. There is 1500 vdc
- and 600vdc around for "local" service, but all long-haul is AC.
-
- BTW, some of the newer subways use 750vdc.
