The landmines damaged the tracks at two places in the Saranda forest areas bordering Jharkhand, about 80 km from Rourkela, GRP sources said.
The goods train service which transports iron ore to the Rourkela Steel Plant has been suspended.
Buses between Rourkela and Jharkhand also went off the roads.
The tracks were being repaired after the GRP, RPF and Railway Engineering staffs went to the spot.
