Tål veteranloken 18 kV? (Elektrifiering/elektrisk drift)

Minns att jag sett någonstans, att 1923 sattes nominell spänning till 16kV. Har dock glömt var.

I SJ 75års jubileumsskrift från 1931 beskrivs att elektrifieringarna av Malmbanan och Stockholm-Göteborg utfördes för nominell spänning på 16000 Volt.
För den senare banan övervägdes också 3000 Volt likström men det skippades till förmån för samma system som malmbanan. Någon gång senare tycks den nominella spänningen ha sänkts till 15 kV men den kan alltså variera uppåt och nedåt en del.
