I think it's safest to travel by train now. After all, trains are disinfected there. Each train is thoroughly disinfected before it leaves the station. Bedding, which is issued to passengers for rest and overnight stays on the train, also undergoes additional sanitization. Personnel at railway stations and in trains must wear masks and undergo a body temperature check before going on shift. All railroad workers have been specially trained - they know how to take care of the passenger, who has on the way the symptoms of acute respiratory viral infections, and those around them. And if you are a tourist, for example, and do not know where to look for all the information, you can find it at dbfahrplan.com.
