NRS-22474 | Glass Plate and Acetate Negatives with "S" [Signals Branch] Prefix

These are ½ size glass plate negatives and acetate negatives. The images in this series with 'S' prefix [Signals Branch] are of Signals and Telegraph equipment. Series and item end dates are circa only. Custody History From 1955 until 2000 the State Rail Authority of New South Wales maintained an 'in house archives' consisting of the archival records of the Authority, its predecessor agencies and the private railway companies taken over by the government. The date ranges of the records were from 1849 until 2000. When the decision was made to close the 'State Rail Archives' the parts of the collection that were required as State archives were transferred to the State Records Authority of NSW. Those record series were incorporated into the State Records series system of archives control and were re-numbered. This series was formerly part of the State Rail Archives collection where it was identified as series R190. It may have been viewed in the State Rail Archives as series R190 and could have been previously cited as such in notes by researchers at State Rail Archives or in publications or unpublished works.

保管沿革：1955年至2000年间，新南威尔士州铁路局（State Rail Authority of New South Wales）设立内部档案馆，馆藏涵盖该局、其前身机构及政府接管的私营铁路公司的档案记录，档案时间跨度为1849年至2000年。在决定关闭“州铁路档案馆（State Rail Archives）”时，符合州档案收录要求的馆藏部分被移交至新南威尔士州档案管理局（State Records Authority of NSW）。该批档案系列被纳入州档案管控的序列体系，并重新编号。本系列原隶属于州铁路档案馆馆藏，当时编号为R190系列。该系列在州铁路档案馆期间可能曾以R190系列的身份被查阅，且此前可能已被州铁路档案馆的研究人员在笔记、出版物或未刊作品中以此编号被引用过。
