( CNN ) -- Two commuter trains collided near Argentina 's capital on Tuesday , killing at least three people and injuring hundreds more . Rescuers rushed to evacuate people and tend to the wounded , who were lined up on stretchers near the smashed train cars . At least 315 people were hurt in the accident , which occurred just after 7 a.m. in a western suburb of Buenos Aires , Argentina 's state-run Telam news agency reported . `` The lights went out suddenly , and there was an explosion . I was in the last car . The only thing you could hear were screams , '' passenger German Garay told Telam . `` People became desperate to get out . They were stepping on each other . '' Argentine President Cristina Fernandez de Kirchner expressed solidarity with the train crash victims and their families in a speech at an event in Buenos Aires Thursday night . `` In addition to solidarity and pain , I feel anger and impotence , '' she said . `` Because the truth is , we are putting everything ( into the train system ) , not just economic resources and investment , but also time and human resources . When things like this happen , it hurts all of us . '' A preliminary investigation indicates that one train rammed into another train that was stopped between stations , Telam said . Authorities said they were still looking into what caused the collision , which occurred near the Castelar stop on the Sarmiento line . `` We want to determine if it was foul play or an accident , '' Transportation Minister Florencio Randazzo told reporters . `` If it could have been avoided , it was not accident , and there will be one or more people responsible . '' Transportation officials said the trains had been checked by mechanical engineering inspectors in March . Thursday 's crash happened nearly 16 months after a commuter train on the same rail line crashed into a barrier at a station in Buenos Aires , killing 50 people and injuring hundreds . That crash sparked a criminal investigation . More than two dozen suspects , including former government officials , are awaiting trial , accused of mismanagement and defrauding the public . Now a government consortium oversees the train line , rather than a private company . But family members of victims of the 2012 crash said Thursday 's collision was a sign that little has changed . `` It is the same and it keeps getting worse . As the days pass , the trains get older , '' said Maria Lujan Rey , whose son died in the 2012 crash . And government officials , she claimed , continue sending trains to corrupt companies for repair . `` So what do you think could have changed ? '' she said . `` Nothing . '' Journalist Ivan Perez Sarmenti and CNN 's Miguel Escalona contributed to this report .
