The activists of Viduthalai Chiruthaigal Katchi (VCK) blocked the Madurai-Shencottah train for more than half an hour, police said.
The agitators sought the state government to help the fireworks manufacturing units in and around this town, national hub for fireworks, resume work.
A large posse of police personnel has been deployed after the VCK announced its support for the nearly 860 units, which had remained indefinitely closed since December 26 over their charter of demands.
Their other demands include early hearing of a case in the Supreme Court related to nationwide ban on sale, possession and bursting of crackers to prevent air pollution.
The striking workers had urged the central government to make a small amendment to the Act, just as they did to allow jallikattu (bull-taming sport).
Meanwhile, sources in the industry said business worth Rs 250 crore has been affected due to the 13-day-long strike.
Local traders and autorickshaw operators have also extended their support for the fireworks industry.
