This settlement grew up around a railway junction, and is these days primarily known as a place where you have to change trains.

Hallsberg was declared a municipalsamhälle (a type of borough within its municipality) in 1883 and got the title of a market town (köping) in 1908.

Hallsberg is famous for its huge classification yard and for the large train station.

The reason for this is that railways (from practically all cardinal directions) to and from Stockholm, Gothenburg, Mjölby, Örebro and Karlstad join here.

It was drawn by the architect Ferdinand Boberg, and contains wall-paintings by Carl Larsson, depicting the Bergöö family and other well-known people of Hallsberg.
