"Protestors blocked railway tracks in Patna, Gaya, Darbhanga, Hajipur and Bhagalpur, Madhepura, Nalanda, Jehanabad, disrupting train services. The BJP workers have been forcibly stopping trains at various railway stations since morning," a railway official said.
BJP leaders had appealed Thursday to avoid travelling by trains Friday.
Senior BJP leader and former deputy chief minister Sushil Kumar Modi also requested passengers to cancel their train tickets.
The party had given call for rail blockade last week after Bihar chief minister Nitish Kumar had called a shutdown in Bihar March 2 to protest the denial of special category status.
