Led by TMC MLA Jatu Lahiri, the agitators blocked the tracks between 10.35 am and 11.45 am between Santragachi and Ramrajatala claiming that the ongoing expansion of a railway yard there was affecting the drainage system in the area, SER sources said here.
Some of the travellers got delayed in attending to their works due to the obstruction on the tracks.
"We were forced to take the path of agitation as the railway authorities blocked a sewerage line that passes under the railway tracks since the last few days, affecting sewage in six wards of Howrah Municipal Corporation," Lahiri said.
Officers of the SE Railway assured the agitators that the expansion work would not affect the drainage system.
