A train sits beneath the carriage of another train after they collided at a station in Alfarelos, Portugal, on Jan. 22.

Emergency services say a high-speed intercity train rear-ended a local train waiting to enter a station in central Portugal, derailing several carriages leaving a pile of wreckage on Portugal’s main north-south line, slightly injuring 21 people. Officials said the local train was waiting to pull into a station near Coimbra, 120 miles north of the capital, Lisbon, when the northbound intercity train slammed into it from behind at 9.15 p.m. (2100 GMT) on Monday
