Mr. Enke played for the German club Hannover 96. Team president Martin Kind confirmed his death, and German police later released a statement saying a man had been fatally injured after being struck by a train last night.

Mr. Enke had been diagnosed with a bacterial stomach ailment and missed nine weeks before returning 11 days ago and playing two Bundesliga games.

He had not been selected for Germany’s exhibition games against Chile on Saturday and Ivory Coast on Wednesday. But coach Joachim Loew had said Mr. Enke remained the leading candidate to be Germany’s goalie at next year’s World Cup in South Africa.

Mr. Enke and his wife, Teresa, lost their 2-year-old daughter to a heart ailment in 2006. In May, the couple adopted a girl, who is now 8 months old.

Team manager Oliver Bierhoff said: “We are all shocked. We can’t find the words.’’
