Active fight against infection in the buses

How can local transport companies signal to their passengers that the bus ride is not a Corona Ascension Command? By doing more than what is currently required by law. The Stadtwerk from Regensburg and the Hamburger Hochbahn provide two examples.

“Das Stadtwerk.Mobilität” and “das Stadtwerk.Fahre und Technik” from Regensburg have renewed the antimicrobial Dyphox coating in all inner-city buses across the board. With this special paint, germs of all kinds – including corona viruses – are killed on various surfaces for at least one year. “This is intended to ensure that all passengers continue to feel safe when using public transport,” says Regensburg.

At the end of 2020, the antimicrobial and environmentally friendly coating was applied to surfaces such as handrails, door opening buttons or armrests in all of Regensburg’s 120 city buses for the first time. The driver’s workplaces were also equipped with it. According to the manufacturer, a company from Regensburg, the technology frees surfaces from viruses and bacteria – just with oxygen and light. Due to the positive experiences and various studies, the Regensburg company has again invested in this new hygiene technology.

In Hamburg, the companies Hochbahn and VHH rely on filters. In a few months they want to have their entire bus fleet equipped with antiviral filters. Currently, 85 percent of the approximately 1,700 vehicles are already equipped with antiviral filters.

High air exchange in the buses

The new filter technology supplements the already very effective ventilation system in buses and the central door opening at every stop introduced during the pandemic. Even without a filter, the air change achieved in buses with standard equipment corresponds to at least four times the recommendation for regular ventilation in residential buildings. The antiviral filters also increase safety, as they reduce viral pollutants in the air by 99 percent, according to Hochbahn. (wa)
