"The Coal Ministry communicated that the situation was reassessed by the DGMS (Director General of Mines Safety), which declared that 14 kilometres of the 35-kilometre-long railway line is unsafe and said the movement of trains on this line needs to be stopped immediately," Mr Jamshed said.
He said the fire had reached just below the tracks in Bansjora railway station limits. The fire is said to have spread between Sijua and Katrasgarh and between Katrasgarh and Sonardih.
The decision has affected several trains including 26 Express trains such as Ranchi-Howrah Shatabdi Express, Ranchi-Bhagalpur Vananchal Express, Dhanbad-Kerala Alappuza Express, Ranchi-Gorakhpur Maurya Express, Dhanbad-Bhubaneswar Garib Rath Express, Ranchi-Jayanagar Express, Hatia-Patna Patliputra Express and Ranchi-Dumka Express.
The Dhanbad-Chandrapur section is also a major route for freight trains. Coal for thermal power plants across the country is transported from there. The underground coal mine fire has been raging in the area since the last century. It was first detected in 1916.
