Peak hour train traffic has been badly affected in Mumbai on Tuesday as hundreds of students and job seekers, demanding railway jobs, sat on the rail tracks in the heart of the city - between Matunga and Dadar. The students, mainly those who have cleared the railway apprentice exams, have been protesting since 7 am between the Matunga and Chhatrapati Shivaji Maharaj Terminus (CSMT) stations in south Mumbai, blocking trains to one of the city's busiest business centres. The railways have been forced to stop running suburban and express trains.
