Students belonging to All Assam Students' Union, All Rabha Students' Union, All Bodo Students' Union, All Assam Koch Rajbongshi Students' Union and Bengali Chatra Federation among others, blocked the tracks at Dudhnoi from 6:30 am to 10:30 am.
There was, however, no report of any untoward incident so far, official sources added.
Two trains Capital Express from Guwahati to Danapur, and Chilarai Passenger train from Bongaigaon to Haiborgaon were detained near Dudhnoi for several years.
The blockade was held to protest against the kidnapping of Kameswar Rabha, headmaster of Hatigaon Belpara LP School, and Sorit Rabha, by suspected Garo National Liberation Army (GNLA) from Dawaguri village bordering Meghalaya on May 13 last.
