About Connecting Stockholm

As the operators of Stockholm's subway, we run a community-critical operation where safety, accessibility, and punctuality are at the core. We combine experience and innovation to create a subway that is safe today and sustainable for the future.

Every day we meet hundreds of thousands of travelers, and through warm, respectful, and professional interactions, we create a travel experience where everyone feels warmly welcomed and safe.

We believe in the power of collaboration, in relationships that build trust, and in leadership characterized by professionalism, heart, and commitment.
