Over 3,200 people work at SSB, many of them in the "behind the scenes" workshops. They ensure that vehicles are checked, repaired, cleaned and are safe to drive. But you can meet around 1,200 SSBers every day on the streets of Stuttgart driving the cable cars and cog railways, around 170 light rail vehicles and over 260 buses. The track builders and traction current specialists are also active on the network every day, a little less conspicuously and as a matter of course. They are less conspicuous on the street because they are often out and about at night when there are no more trains running during the shutdown. You can also meet the SSB at the bus stops when they are being cleaned or when weather protection or a ticket machine is being repaired there.

The people of Stuttgart can also encounter their "tram" in the customer and service centres, as advisors in front of the ticket machines or in the vehicles themselves when checking the ticket. That's what it's still affectionately called in Stuttgart or, especially by the younger people of Stuttgart, "U-Bahn". Compared to other cities, the very special feature of the SSB is that it has consistently replaced the tram with a modern light rail system and can therefore offer its Stuttgart residents very good local transport quality: fast, safe and comfortable.

The SSB owns a neat tram museum in Bad Cannstatt, the large Waldaupark conference center is on the Waldau, the small Killesbergbahn at the Höhenpark Killesberg delights young and old - and the subsidiary SSB-Reisen ensures that many people in Stuttgart go on vacation every year.
