NRS-15273 | Returns of kilometres run by each locomotive

This series comprises "standard No. 11 statistical returns" for State Rail locomotives showing the locomotive class and number, date introduced, kilometres travelled for a particular period, total kilometres travelled and service dates. The distance figures where drawn from Hasler Speed Tapes that formed part of the locomotive's odometer recording system.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 R59. It may have been viewed in the State Rail Archives as series R59 and could have been previously cited as such in notes by researchers at State Rail Archives or in publications or unpublished works.

本数据集收录新南威尔士州属铁路机车的《第11号标准统计报表》，内容涵盖机车车型与编号、投入使用日期、特定运营周期内的行驶里程、总行驶里程以及服役日期。上述里程数据取自哈斯勒测速带（Hasler Speed Tapes），该设备为机车里程表记录系统的组成部分。

保管历史：1955年至2000年间，新南威尔士州铁路管理局（State Rail Authority of New South Wales）设立内部档案馆，馆藏包含该局、其前身机构以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。当决定关停「州属铁路档案馆」时，符合州级档案保管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理体系，并重新编目编号。

本数据集原隶属于州属铁路档案馆馆藏，当时编号为R59系列。此前在州属铁路档案馆中，该数据集曾以R59系列的身份供查阅，且可能曾被该馆研究人员在笔记、已出版或未出版作品中以此编号被引用。
