NRS-9940 | Miscellaneous plans of Sydney Harbour Bridge Approaches and the City Railway

This series consists of plans drawn up by the Department of Public Works and the New South Wales Government Railways detailing the approaches to the Sydney Harbour Bridge, track layout and line locations, details of the underground city railway and some stations such as Circular Quay and Central Railway Station. These plans were transferred to the Metropolitan Water, Sewerage and Drainage Board at an unknown time and were renumbered into an ‘S’ and a ‘W’ sequence. Some of these plans have been annotated by the Metropolitan Water, Sewerage and Drainage Board to show such things as sewers, drains, down and up lines.Most of the plans in this series were part of the original sets 102.C; 103.C; 104.C; 105.C and 107.CRelationship to other series The plans of the Sydney Harbour Bridge appear to have been dispersed into various series possibly determined by work requirements or reference needs. Other plans in the set 103.C. have survived in series NRS 12683 that also contains several plans of the set 106.C.

本系列图纸由公共工程部（Department of Public Works）与新南威尔士州政府铁路局（New South Wales Government Railways）编制，内容涵盖悉尼海港大桥（Sydney Harbour Bridge）引桥设计、轨道布局与线路走向、地下城市铁路细节，以及环形码头站（Circular Quay）、中央车站（Central Railway Station）等站点的相关图纸。

上述图纸于未知时间移交至大都会供水、排水和排污委员会（Metropolitan Water, Sewerage and Drainage Board），并被重新编号为以'S'与'W'为标识的序列。

部分图纸由该委员会加注标注，用以标注下水道、排水渠、上下行线路等相关信息。

本系列绝大多数图纸均源自原始图集102.C、103.C、104.C、105.C及107.C。

与其他系列的关联：悉尼海港大桥相关图纸似乎已分散至多个系列，其分类依据可能为工作需求或查阅用途。原始图集103.C中的其余图纸留存于系列NRS 12683中，该系列同时包含106.C图集的部分图纸。
