Statens modelljärnvägar (Elektrifiering/elektrisk drift)

av Lars-Henrik Eriksson, Sunday, October 13, 2013, 15:53 (4158 dagar sedan) @ Gunnar Ekeving

som vi sett i en tidigare tråd var affärsverket Statens Järnvägar från 1920-talet och framåt ofta representerat på utställningar. Då var ett diorama med modelltåg vanligen en centralpunkt i utställningen.

I flera fall tycks man ha haft en modell av tågfärja; denna ritning från Sveriges Järnvägsmuseum visar kopplingsschema till ett lok på en sådan modellanläggning:

Jag fattar inte den där ritningen alls. Ett lok som har flera fasta anslutningar till räls och signaler??
