Growing up, Siw rarely visited Flåm, but between the ages of 15 and 21, she spent more time there. An early relationship with a boy who worked on the trains drew her into the world of railways - a casual joke from his brother about becoming a conductor, like her boyfriend, planted a seed that would eventually shape her career path.
On September 1, 1986, Siw officially started her railway career - first in Oslo, where she worked for nine years. It was a big change, moving to the "big city" with her regional dialect, but she enjoyed her time there. Colleagues became friends and Siw became part of the Railway community. Still, life became challenging as a single mother of two. She eventually returned home, living with her mother and sister in Aurland.
