Hefazat-e-Islam's hartal in the district had disrupted train services on Dhaka-Sylhet and Dhaka-Chittagong routes
Train communications between Dhaka-Sylhet and Dhaka-Chittagong have resumed after 11 hours.
Trains began operating through Brahmanbaria at 10pm on Sunday, reports Prothom Alo, quoting Brahmanbaria Railway Station Master Shoeb Ahmed.
Earlier, Hefazat-e-Islam's hartal in the district disrupted train services on these routes. Several trains remain stranded in different stations due to the suspension.
At least 10 people were injured after members of the Islamist group hurled bricks on the Chittagong-bound intercity Sonar Bangla Express train in Brahmanbaria on Sunday morning.
They also set fire to a railway bridge between Ashuganj and Brahmanbaria.
On Friday, Hefazat called the daylong nationwide hartal for Sunday, protesting against the killing of its activists by police and the attack on them by ruling party supporters during demonstrations against Indian Prime Minister Narendra Modi’s visit to Bangladesh.
During Sunday's strike, Hefazat leaders and activists turned violent in different parts of the country -- vandalising and torching vehicles in Dhaka and Rajshahi, and attacking government offices in Brahmanbaria.
