BUENOS AIRES, Argentina (AP) -- An Argentine court is charging two former government officials and the owners of a train company in connection with a crash that killed 51 people last year.
The Buenos Aires federal court on Friday ratified charges previously filed against former transportation secretaries Juan Pablo Schiavi and Ricardo Jaime.
The court also charged Sergio and Mario Cirigliano, owners of the Buenos Aires Train company.
The court revoked an order by a lower judge last year that relieved the train's machinist and the ex-head of the National Transportation Regulation Committee of any blame.
The train was packed when it slammed into a metal barrier at Buenos Aires' Once station on Feb. 22, 2012.
It marked one of the worst tragedies in Argentina's deteriorating rail system.
