It is not clear what really led to the accident as a portion of the rail got disassembled under the weight of the locomotive.
There were 66 wagons carrying iron ore from the Tokadeh to Buchanan.
About 38 wagons were detached from the locomotive during accident.
This is the first time in almost four years, since another locomotive derailed between Nimba and Bong, leaving ore scattered all over the scene of the accident.
As was with the previous accident, this one recorded no casualty, except that some of the wagons disconnected from the locomotive and dumping the iron ore on board the wagons.
