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

På Roslagsbanan.

ja, elektrifiering med 1500 V likström där var naturligt eftersom förortssträckorna närmast Stockholm redan tidigare elektrifierades med likström, dock med lägre spänning. Dessutom var ju Roslagsbanan pga spårvidden ett avgränsat system, så antagligen fanns inga stora vinster att göra på att lägga om till enfasdrift
