Pro-Russian rebels who had been guarding the main impact site also appeared to have left, with about a dozen stretchers, paper masks and plastic gloves abandoned at the scene.
Poles marking locations where bodies had been found in the field had also been removed.
Russian news agency Ria Novosti said a train with five refrigerated carriages carrying the corpses departed today from a station close to the main crash site and was heading for rebel stronghold Donetsk.
Monitors from European security body OSCE inspected the carriages at Torez station, Ria Novosti said, quoting them as saying a total of 198 bodies were on board -- presumably recovered from across the vast crash site.
