69KV?[edit]

The article makes mention of Amtrak's 69KV transmission. All I've ever read talked about 132/138KV. What does this refer to? 166.84.1.1 (talk) 01:55, 29 January 2013 (UTC)[reply]

Each circuit is composed of one wire +69Kv respect to ground and another -69Kv with respect to ground and 180o out of phase with the first. Sturmovik (talk) 02:39, 29 January 2013 (UTC)[reply]
