Dhanbad Superintendent of Police (Railway) Asim Vikrant Minz said tracks were blown up between Chichaki and Karmabad stations under Dhanbad Railway Division at 12.40 am, shortly after the "bandh" began at midnight.
Several long-distance trains including Kalka Mail, three Rajdhani Express trains, Hatia-Patna Express and Howrah-Dehradun Express stopped for some time, railway officials said. The schedule of freight trains was also regulated at different places.
Dhanbad Senior Divisional Commercial Manager AK Jha said train services on the route were restored after 7.40 am. Railway officials and personnel of the Railway Protection Police from Hazaribagh rushed to the spot immediately after the explosion, the police said.
A report from Lohardaga district said the strike drew partial response as most shops and markets were open, but long-distance buses did not run. Tight security arrangements have been made in Lohardaga and Maoist-hit Khunti districts, police said.
The Maoists called the "bandh" in protest against amendments to old land laws in Jharkhand, namely the Chhotanagpur Tenancy Act, and the Santhal Pargana Tenancy Act.
