According to the company, the disruption to the railway in northern Germany has been resolved.
"Long-distance traffic in the affected areas is currently starting again," writes the railway on its website.
Due to the after-effects, however, delays and cancellations could continue.
According to the company, a high utilization of the first trains is to be expected.
Countless travelers were stranded at the train stations on Saturday morning because all long-distance traffic and some regional traffic were stopped in large parts of northern Germany.
Bremen, Hamburg, Lower Saxony and Schleswig-Holstein were affected, as Deutsche Bahn wrote on Twitter.
In international train traffic, IC trains from/to Berlin towards Amsterdam were completely canceled.
The company recommended travelers traveling between Berlin and North Rhine-Westphalia and between Berlin and Baden-Württemberg or Switzerland to use connections via Erfurt and Frankfurt/Main.
According to the railways, the reason for the chaos was a technical fault in the train radio.
What exactly led to this remained open for the time being.
In general, Deutsche Bahn recommended that its travelers inform themselves shortly before planned trips via www.bahn.de/reiseauskunft, via the "DB Navigator" app or by calling 030/2970.
The Bahn website said: "As soon as we have new information, we will keep you updated here."
