Railway communication was completely disrupted between Lumding and Badarpur with the bandh supporters damaging the tracks near Bageter station, the police said.
Supporters of NC Hills Indigenous Student Forum (NCHISF), which has given the Dima Hasao bandh call, also set ablaze a railway bridge near Migrendisa station under Haflong police station in Dima Hasao district.
Essential supply of goods to Barak Valley and neighbouring states of Tripura, Manipur and Mizoram were affected.
All passenger and goods trains had been cancelled as a precautionary measure since the beginning of the shutdown on February 26 last, official sources said.
The shutdown was called by NCHISF, demanding bifurcation of Dima Hasao into two districts and protesting over renaming of NC Hills to Dima Hasao.
The shutdown has almost paralyzed normal life with almost all establishments remaining shut for the fourth consecutive day in the district on Saturday.
Since February 26, banks, post offices, markets, other commercial establishments and government offices were closed and vehicles off the roads.
The shutdown was marred by violence on Friday with at least 15 persons, including a woman police officer, seriously injured in a clash between police and bandh supporters at Mahur railway station.
Friday's clash took place when the police tried to lift a rail blockade by agitators.
The district administration has been trying to convince the NCHISF to withdraw the shutdown and maintain peace.
