In 2002, the Sognsvann Line was closed during the summer vacations due to improvements of the track and third rail. In 2008, the line was closed for approximately one week, due to leaves that had covered the tracks. The operation of the line was replaced by buses that served temporary stops in Nordbergveien and Sognsveien. In 2010, a truck was stuck under the train bridge between Holstein and Kringsjå over Carl Kjeldsens vei. The bridge was damaged, and allowed for only one-way-traffic for two weeks. Half the trains had to stop at Berg in the meantime.
