At least two people sustained minor injuries in an explosion at a train station in the southern German city of Augsburg, police reported on Wednesday.
The station building and Track 1 are currently closed, a police spokesperson told daily Bild on Wednesday morning.
Train services have also been disrupted and are being rerouted to other tracks.
Augsburg is a regional transport hub and is around 55 kilometres from the Bavarian capital Munich.
Explosives experts from the Bavarian State Criminal Police Office are on the scene, according to police. The cause of the explosion is still unknown.
Police are also investigating suspected sabotage at an Amprion power substation in Bergheim, in the western state of North Rhine-Westphalia, public broadcaster WDR reported.
A short circuit knocked several power lines out of operation, but the wider electricity supply was unaffected.
Police suspect the incident was deliberate rather than the result of a technical fault. Investigators are examining whether it could be connected to suspected sabotage in Brandenburg.
Suspected sabotage at Brandenburg power plant
The incident in Bergheim came after unidentified suspects carried out a sabotage attack on an electrical facility at a major power plant in the eastern state of Brandenburg on Tuesday, according to authorities.
Brandenburg Interior Minister Jan Redmann said the suspects used projectile devices to cause a short circuit in an extra-high-voltage line near the Jaenschwalde power plant.
“We cannot currently confirm that an explosive device detonated there or anything of that sort,” Redmann said.
Police earlier said devices apparently made from pyrotechnics had been found at an electrical substation, although reports differed over whether any of them exploded.
Bild reported that police had confirmed an explosion and discovered several improvised incendiary and explosive devices, not all of which detonated.
Public broadcaster RBB, however, quoted police spokesperson Stefanie Pilz as saying that no explosion had occurred.
Grid operator 50Hertz said unknown perpetrators damaged several transmission lines, briefly interrupting operations. All lines were later restored, and the public electricity supply was unaffected.
The Jaenschwalde facility near the Polish border is one of Germany’s largest lignite-fired power stations.
