The rebels triggered a landmine blast damaging a stretch of railway track at a place between Renjeda and Roxy, about 90 km from the steel city of Rourkela, Railway Protection Force (RPF) sources said.
Nobody was injured in the incident that took place in Rourkela-Kirbur section, they said, adding no damage was caused to a goods train on the route as its vigilant driver stopped it after noticing the damaged track.
Movement of goods trains carrying iron ore and other materials to Rourkela Steel Plant and the only passenger train between Rourkela and Kirbur was affected, officials said.
The rebels also set afire at least 12 dumpers at Chunaghati on National Highway No. 215 under Koida police station in Sundargarh district.

Life was also affected in other districts including Malkangiri, Rayagada, Koraput, Gajapati and Kandhamal during the bandh as buses stopped plying and most private vehicles went off the roads in these regions, they said.
A large number of people were stranded in Kalimela, Motu, Padia and MV-79 areas of Malkangiri due to suspension of bus services, they said.
Shops and business establishments also downed their shutters in many places, particularly in semi—urban and rural areas.
