omformarstationer (Elektrifiering/elektrisk drift)

av Kjell Aghult @, Friday, April 08, 2011, 09:36 (4997 dagar sedan) @ Anders_W

SJ gav ut en bok om Elektrifieringen av stambanorna (osäker på titeln) på 40-talet. lut.Den kom i faksimil från något av järnvägsförlagen för bara några år sedan. Mycket läsvärd.

Edit:
Hittade den!

Veterligen är denna skrift enda tillgängliga historik (Fastän den är gammal,
utgiven 1932). Samlade listor över omformarstationerna fick länge inte utges, av totalförsvarsskäl. Detta förbud hävdes först efter kalla krigets slut.
