In Delhi, the Indian Youth Congress workers stopped a train at the Shivaji Bridge railway station near Connaught Place to push for their demand for a rollback of the Agnipath defence recruitment scheme.
The track was cleared by the police and security personnel and train movement resumed after about half an hour, sources said.
Several protesters were detained as police personnel tried to remove them from the tracks and the station, a senior police official added.
Youth Congress president Srinivas BV said, "The government needs to roll back the Agniveer scheme. The Youth Congress will fight for the unemployed youth who want to serve the country."
IYC members also staged protests at nearby Connaught Place.
Northeast Frontier Railways cancelled at least 26 trains due to violent agitations against the 'Agnipath' scheme and floods that wrecked several places in Assam, an NFR official said, adding many trains have also been short-terminated, short-originated, diverted or rescheduled.
Besides the trains cancelled on Monday, another five have also been cancelled for Tuesday, NFR chief public relations officer Sabyasachi De said.
He said north-bound trains from Guwahati were mostly cancelled or changes were made in their schedule due to the violent agitation against 'Agnipath' in Bihar which lead to the burning of coaches and damage to railway properties.
