It was a defunct rail transit point on the Bangladesh-India border. The corresponding station on the Indian side is
Radhikapur railway station in
Uttar Dinajpur district, West Bengal. The transit facility in the Biral-Radhikapur sector had remained suspended since 1 April 2005. The railway track on the Indian side has been converted to
broad gauge while that on the Bangladesh side remained
metre gauge. The Radhikapur-Birol rail link was put back in operation in April 2017. As per the Memorandum of Understanding entered into by Bangladesh and India on 15 August 1978 it was agreed to facilitate overland transit traffic between Bangladesh and Nepal. An addendum was made on 6 September 2011, to add new rail routes for facilitating overland transit traffic between Bangladesh and Nepal. The addendum read:"1."Traffic in Transit” to/from Nepal and Bangladesh shall move through Indian territory by rail using
Singhabad Railway station in India and Rohanpur Railway station in Bangladesh with their existing facilities. To ensure expeditious and smooth flow of such movement, necessary infrastructural facilities shall be provided by the two Parties within their respective territories. "2.The existing rail route through Radhikapur Railway station in India and Birol Railway station in Bangladesh which has been suspended shall be brought into operation by converting Bangladesh portion into broad gauge. In this case, both the routes (proposed and the existing) shall be used for Nepal Transit Traffic by rail for additional operating convenience."

Rohanpur-
Singhabad transit point in November 2011. ==Track conversions==
