Abstract: The volume comprises telegrams, despatches, correspondence, memoranda, and maps, relating to the two topics contained in the volume on railway development in Persia. The first topic is the Khoremmabad-Dizful-Mohammerah railway and the survey required to assess its practicability and probable cost.The volume includes (ff 97-102) 'Russia. No. 1 (1907). Convention signed on August 31, 1907, between Great Britain and Russia, containing 'Arrangements on the subject of Persia, Afghanistan, and Thibet.' The volume also includes (ff 179-194) the 'Report on the Proposed Railway from Khor Musa to Khurramabad' by Arnold Talbot Wilson, Acting Consul for Arabistan.The second topic is the Persian Railway Syndicate and the accompanying negotiations over its financial structure including the impact of manouveres by Great Britain and Russia and the increased likelihood of Persia gaining access to outside borrowing.Each part includes a divider which gives the subject and part numbers, year the subject file was opened, subject heading, and list of correspondence references contained in that part by year. This is placed at the back of the correspondence.Physical description: Foliation: the main foliation sequence (used for referencing) commences at the first folio with 1, and terminates at the inside back cover with 401; these numbers are written in pencil, are circled, and are located in the top right corner of the recto side of each folio. An additional foliation sequence is present in parallel between ff 201-271; these numbers are written in coloured pencil, but are not circled. A previous foliation sequence between ff 290-399, which is also written in pencil and circled, has been superseded and therefore crossed out. The foliation sequence does not include the front cover, nor does it include the leading flyleaf.
