In pre-independence days, a metre gauge line running via Radhikapur, Biral, Parbatipur, Tista, Gitaldaha and Golokganj connected Fakiragaram in Assam with Katihar in Bihar.
It reached Katihar in 1888-89 and in 1909 it reached Amingaon on the banks of the Brahmaputra, which could be crossed by ferry to reach Guwahati.
