Ultras of the proscribed CPI (Maoist) damaged railway tracks and torched two buses to enforce their 48-hour North Bihar Bandh that began on Thursday.
Two sleepers were damaged and at least 25 clippers removed between Kurahni and Turki stations on Muzaffarpur-Hajipur section of the East Central Railway affecting rail traffic since morning, ECR Chief Public Relations officer Dilip Kumar said.
Several trains including Maurya Express, Vaishali Express, Bihar Samparkkranti Express and Muzaffarpur-Hajipur passenger train were affected, Kumar said adding that engineers were working to repair the tracks.
The Maoists also set on fire two buses at Parsotinpur Bazar under Maker police station of Saran district late last night, police said.
About 50 ultras raided the buses, set the parked buses afire and fled leaving behind leaflets asking people to make the bandh successful.
The bandh call was given in nine North Bihar districts by the Maoists against price rise, alleged police excesses and 'anti-people' policies being pursued by the goernment.
