The line, which is only used by freight trains, was closed for several hours after the attack on Sunday in Essen, western Germany.
Its security services Germany are conducting an investigation after unknown persons cut cables of the state railways, an action considered as a second sabotage at the expense of Deutsche Bahn within an equal number of months.
The line, which is used only by freight trains, was closed for several hours after the attack in Essen, western Germany, on Sunday, a Deutsche Bahn spokesman said, confirming a report by Der Spiegel magazine.
The spokesman said the impact was very limited as the line is rarely used on Sundays and had been fully repaired by the evening.
In October, fiber optic cables were cut in three places and authorities said it was sabotage.
Due to the cutting of the cables, all train services in northern Germany were interrupted for three hours.
Police later said they were not ruling out the possibility of politically motivated sabotage but there was no indication of any foreign state involvement in the case.
