New Delhi: The Indian Railways has kick started a massive effort to digitise its archives across the country that will cover about 25 million pages of railway history. As an initial step, 2.2 million pages of the archival material of the National Rail Museum (NRM) in New Delhi and Rail Museum at Tiruchirapalli in Tamil Nadu will be archived, an official told PTI. In a decision taken last week, the Railway Board has begun what could be the largest digitisation of archives by any organisation in India, he said. Archival materials consist of documents, orders, time tables, photographs, technical diagrams, engineering drawings, letters, annual reports, books, manuals. (PTI)
