NRS-22451 | Chief Mechanical Engineer's Contracts files

These files comprise correspondence of the Chief Mechanical Engineer's Design Office, concerning the preparation of specifications, issue of tenders, letting of contracts, and completion of contracts for the construction and/or supply of locomotives, rolling stock, and other equipment. Also included are unnumbered selective maintenance contracts, usually connected to a major supplier. Most files are in an annual single number system, some bearing a year and "E" [extension] number. Custody HistoryFrom 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 R91. It may have been viewed in the State Rail Archives as series R91 and could have been previously cited as such in notes by researchers at State Rail Archives or in publications or unpublished works.

保管历史：1955年至2000年间，新南威尔士州铁路管理局设立了内部档案馆，馆藏涵盖该局、其前身机构以及被政府接管的私营铁路公司的档案记录。这批档案的时间跨度为1849年至2000年。在决定关闭“州铁路档案馆”时，馆藏中符合州档案要求的部分被移交至新南威尔士州档案管理局。该批档案系列被纳入新南威尔士州档案管理局的档案管控系列体系，并重新进行了编号。该档案系列原隶属于州铁路档案馆馆藏，当时被编号为R91系列。该系列在州铁路档案馆中曾被归类为R91系列，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进行引用。
