From archival materials, Mrs. Ajdin Fevzije Brace publishes the edition of the “Yearbook” of the Yugoslav State Railways from 1937, which contains personal data of the staff of the state railways, including: Ministry of Transport, General Directorate of JDŽ, regional directorate Belgrade, regional directorate Zagreb, regional directorate Ljubljana, regional directorate Sarajevo, and regional directorate Subotica. Since the publication is extensive (990 pages), I am taking this opportunity to publish partial data from the Ministry of Transport, the general directorate of JDŽ, and personal details of the staff of the Sarajevo regional directorate. I hope that the published material will be interesting to the public, especially to both older and younger railway workers, and that it will help identify the names of ancestors or great-grandparents who worked at stations from Bihać to Zelenika, Sarajevo to Užice and Čačak, Doboj to Valjevo, Lašva to Vaku, etc.
