Lyckades stoppa elektrifiering enligt svenskt sytem (Elektrifiering/elektrisk drift)

Har i någon engelsk tidskrift läst om att det lyckades någon att få stopp på att elektrifiera enligt svenskt system på Nya Zeeland. Systemet var omodernt sedan elektrifieringar med 50 eller 60 Hz visat sig fungera utmärkt.

ja, dock dröjde 50 Hz-elektrifieringen flera decennier efter SJ:s insats. På 1950-talet nöjde man sig med att fortsätta bygga ut befintlig elektrifiering med 1500 V likström
