Peak hour train services on Central Railway's main line were disrupted on Friday morning due to a "rail roko" protest by Shiv Sena workers at Mulund against the fuel price hike by the UPA government. Over 50 Sena activists led by a local corporator went on the tracks at the station's Nahur-end at about 9.30 am and blocked movement on all the four tracks. Train movement was completely halted and the GRP men dispersed the mob within a short while. However, the traffic movement was restored by 10 am, the railway police said.
