BK Tåg
BK Tåg AB, trading as BK Tåg, was a Swedish train operator. BK Tåg was one of the first private operators on the Swedish railway network after its liberalisation. When they won the tender for the operation of Krösatågen in 1989 it was the first time a private company competed with SJ in modern times. During the 1990s BK tåg experienced growth in both the passenger and freight sector including regional trains between Borlänge and Malung. In 2002 the company signed several agreements to operate container trains and intermodal transports including transports of LPG and paper. During this time BK Tåg was a serious competitor to more established operators including Green Cargo and CargoNet.
The company experienced losses and struggled to make a profit on passenger operations and filed for bankruptcy in march 2005. 150 employees were left without a job and the passenger contracts left unfulfilled were picked up by other operators including state owned SJ. Some parts of the freight operation were picked up by other juridical entities or were sold of.
