The IED, weighing more than three kgs, two detonators and some fused wire were recovered at Maneswari, at a distance of about one kilometre from Bijni railway station during routine patrolling by a joint team of the police and army personnel, official sources said.
The security forces have cordoned off the area and the IED defused.
Train services have been temporarily halted in the section as security personnel launched a massive combing operation in the area to detect whether any more explosives have been planted or not, sources added.
Meanwhile, security along the railway tracks have been tightened with several trains cancelled or rescheduled in view of the bandh.
