Train station Chandernagore-gare - Public domain photograph.

Chandernagore train station. The railway line and the station were inside British India, just meters outside the boundary of the tiny 9 square km French enclave, part of French India.
Located some 25 miles north of Calcutta on the Hoogly River, tiny Chandernagore with its 26,500 inhabitants in 1918 had virtually become a suburb of Calcutta by then and the French presence was almost nonexistent. Postcard c. 1910-1920.
