Title - German Rail Services Face Disruption after WWII Bomb Found in Berlin

Train services to and from Berlin are likely to be disrupted on Wednesday after a World War II bomb was discovered in a street near the city's main railway station on Tuesday, rail operator Deutsche Bahn said.Some inter-city trains are expected to be redirected or stopped for two hours from 10 a.m. to noon, a spokesman for Deutsche Bahn said. Local city trains aren't likely to be affected, though. "Travellers should be prepared for delays and route changes," the spokesman said. Authorities have yet to decide whether to defuse the 100-kilogram bomb on site, opt for a controlled detonation or remove it.Some 1,100 trains and up to 700,000 passengers pass through the modern station each day. It was opened in 2006.The bomb was found by munitions experts conducting a routine search of a site in preparation of construction work. Unexploded bombs from the Allied bombardment of Germany during World War II are still frequently found. The munitions are getting more difficult and dangerous to defuse because their fuse mechanisms have corroded and become less stable over time.Bomb disposal experts have been warning that bombs will increasingly have to be exploded where they are found because moving them has become too risky. At least two such controlled explosions took place last year, in Munich and Viersen, causing damage to surrounding buildings.
