Säröbanan - förslag till elektrifiering och spårvagnstrafik (Elektrifiering/elektrisk drift)

Egentligen var väl det enda man hade behövt något sätt att säkra trafiken på enkelspåren. Hastigheten för spårvagnar på särskild banvall höjdes ju senare till 60 km/h utan något krav på signalsystem.

Apropå konsulter från SJ så undrar jag om det var en sådan som låg bakom att tunnlarna i Bergsjön fick likströmsspårledningar.
