Maoists went on the rampage on Tuesday as they targeted railway properties in Jharkhand and Bihar besides causing a blast in a school building and destroying mobile phone towers to protest against the Centre's decision to launch an offensive against them.
Armed Maoists blasted railway tracks between Mccluskieganj and Mahuamilan in Jharkhand's Latehar district, which caused 11 rakes of a goods train to derail, Railway PRO Amrendra Das said.
The driver and staff of the train were unhurt, he said, adding the blast disrupted services on both the up and down lines.
The violence occurred during the second day of the two-day shutdown called by CPI-Maoist.
Tracks were also blasted by another group of 100 cadres between Dania and Jageshwarbihar railway stations with overhead traction wires blown off under its impact, Das said.

The Maoists also took hostage six railway officials, the stationmaster and his assistant, but freed them later with a warning not to allow trains to run during a shutdown called by them.
