The B7 wagons had been running for a couple of years and their rear-seating interior had proved less suitable for families. The new carriage therefore received seating groups with seats opposite each other. In addition, a space was added for goods and cargo. / Sources: https://www.jarnvag.net/vagnguide/bf4

The wagons were first given the letter B4, but this was later changed to the more correct BF4 where F stands for cargo space.

The carriages also had a service compartment for the train staff and next to this there was a small space with an information hatch. However, this was short-lived, after a couple of years the space was converted into a phone booth instead. During the 1980s, mobile phones developed rapidly and the carriages were equipped with a telephone that the passengers could use. Anyone who wanted to call had to buy a special phone card in the train's bistro. As personal mobile phones became more common, phone booths became redundant. / Sources: https://www.jarnvag.net/vagnguide/bf4
