Bogestra, Germany


More than 20 locations (train stations and depots)


Train stations' power supply



BOGESTRA AG (Bochum-Gelsenkirchener Straßenbahnen AG) has about 2,200 employees in customer service, rail service, maintenance and administration. BOGESTRA offers the complete service portfolio from one source – from planning of the service offering, repairs of the infrastructure, and maintenance of the trains, to marketing, sales, customer relations and train service. This means it can provide a high quality service.

As one of the biggest local traffic operators in Germany, BOGESTRA is continuously growing its passenger numbers. With its 75 city railways, trams and bus lines, BOGESTRA is transporting over 145 million people per year.

AEG Power Solutions UPS systems protect the electrical power supply at the stations themselves, the control rooms, and the tunnel lighting. Overall, 24 power supply systems were renewed in the last three years at more than 20 stations and depots, including distribution and services.

BOGESTRA selected AEG PS Protect 8.31 systems to replace its previous UPS due to their robustness, reliability and long lifetime. Other factors in the decision were AEG PS’ excellent service and the long product life cycle of Protect 8.31.
