An oil train exploded and caught fire on Sunday in central Georgia, sending plumes of black smoke into the air.
Georgian Interior Ministry spokesman Shota Utiashvili said the train had hit a mine.
He said there were no casualties, but that the blast had also set off explosions at an abandoned munitions dump nearby.
The Russian Defence Ministry declined to comment, saying it was not clear what had happened.
Russia pulled the bulk of its troops and tanks from its small southern neighbour on Friday after a brief but intense war, but built up its forces in and around two separatist regions and left other military posts deep inside Georgia.
The explosion occurred near the village of Skra, 10 kilometres (6 miles) west of Gori.
At the scene, tanker cars lay in a confused jumble, some askew on the railway line and others off the tracks, some lying on their sides, while firemen hosed down the wreckage with foam.
Speaking at the site, the director of Georgia's railways, Irakli Ezugbaia, agreed that the blast was probably caused by a mine. He said an investigation was under way and other mines had been found on the tracks.
Ezugbaia said the train was carrying crude oil from Kazakhstan that was being transported by an Azerbaijani company. It was destined for a Georgian Black Sea port.
Georgia straddles a key westward route for oil from Azerbaijan and other Caspian Sea nations including Kazakhstan, giving it added strategic importance as the U.S. and the European Union seek to decrease Russia's dominance of oil and gas exports from the former Soviet Union.
Meanwhile, near the Black Sea port of Poti, Russian soldiers could be seen at their base on Sunday carrying out excavations.
Russia pulled the bulk of its troops and tanks from its small southern neighbour on Friday after a brief but intense conflict, but still held positions near Poti.
Georgian port officials have said radar, Coast Guard ships and other port facilities were extensively damaged by Russian troops.
A U.S. Navy warship carrying humanitarian aid anchored at the Georgian port of Batumi on Sunday, sending a strong signal of support to an embattled ally.
The much-needed aid and the damaged train were a stark reminder that it will take substantial amounts of aid and many months of rebuilding before Georgia can recover from the war with Russia.
Five days of fighting damaged cities and towns across the country and displaced tens of thousands of Georgians.
