The Northeast Frontier Railway (NFR) has decided to install national flags atop 100 feet tall poles at 38 major stations across the zone during the current financial year, an official said in Guwahati on Wednesday.
The "monumental flags" are being installed as per directives of the Railway Board to improve the aesthetics of the stations and to impart a sense of nationalism and patriotism among the passengers, NFR Chief Public Relations Officer Subhanan Chanda said.
