Old Oak Common (Crossrail XSU10)

Watching Brief and Evaluation - The archaeological works were carried out intermittently from March 2011 until April 2015 and comprised Trial Trenching, Targeted and General Watching Briefs. These took place during the demolition and remodelling of a former Motive Power Depot to create a maintenance depot and stabling facilities for Bombardier Rail who will be responsible for the maintenance and servicing of Crossrail traction and rolling stock. The depot, which was designed by the Great Western Railway's chief locomotive superintendent J. C. Churchward was an important component of, what was at the time, one of the country's most innovative railways. As the first of a number of new locomotive depots built by the Great Western Railway during the Churchward era, the layout of Old Oak Common served as the template for those that followed. The majority of which were closed and demolished in the late 1960s. Until its closure in 2009 the Old Oak Common Depot represented the last remaining 'factory' repair facility on the former GWR network. The below ground remains of a number of structures were uncovered and recorded during the project. These included parts of a large brick built turntable pit, sections of a brick built engine shed as well as a number of below ground brick built inspection pits and the remains of a Second World War Air raid shelter. Non-Listed Built Heritage Recording Report - During 2010 and 2011, Oxford Archaeology, in partnership with Ramboll (OA Ramboll, Crossrail contract C254) undertook a programme of non-listed built heritage recording (NLBH) at Old Oak Common Train Maintenance Depot in Acton, London, on behalf of Crossrail.

考古现场监护与评估：本次考古工作于2011年3月至2015年4月间歇开展，包含试掘探沟（Trial Trenching）、针对性现场监护与一般性现场监护（Targeted and General Watching Briefs）三类工作。所有作业均在原机务段（Motive Power Depot）的拆除与改造期间进行，该改造工程旨在为庞巴迪铁路（Bombardier Rail）打造专属维护段与车辆停放设施，庞巴迪铁路将负责克罗斯雷尔（Crossrail）牵引机车与铁路车辆的日常维护与检修工作。该机务段由大西部铁路（Great Western Railway）首席机车主管J·C·丘奇沃德（J. C. Churchward）主持设计，曾是当时英国最具创新性的铁路网络的核心组成部分。作为大西部铁路在丘奇沃德任职时期新建的首批机车段站之一，老橡树公地（Old Oak Common）的布局方案成为后续同类设施的设计模板，而后者大多于20世纪60年代末关停并拆除。直至2009年正式关停前，老橡树公地机务段是原大西部铁路网络中仅存的“工厂式”系统性检修设施。本次项目中共发掘并记录了多处地下建筑遗存，包括大型砖砌转盘坑的局部区段、砖砌机车库的残体，以及多座地下砖砌检修坑，还发现了一处第二次世界大战时期防空洞（Air raid shelter）的遗迹。
非在册建筑遗产（Non-listed Built Heritage）记录报告：2010年至2011年间，牛津考古事务所（Oxford Archaeology）与伦波尔（Ramboll）合作开展本项目（项目代号OA·伦波尔，克罗斯雷尔合同编号C254），受克罗斯雷尔委托，在伦敦阿克顿的老橡树公地列车维护段实施非在册建筑遗产记录工作。
