This is Mälartåg
The regions of Stockholm, Sörmland, Uppsala, Västmanland, Örebro and Östergötland are making a historic effort to improve regional rail services in the Mälardalen region. Mälartåg is an important part of this initiative, which the regionally owned company Mälardalstrafik is in charge of on behalf of the regions.
