Research conclusions:From the discussions on the maintenance and repair resource sharing, function positioning,construction scale and overall arrangementof theGangchengDepo,t it is concluded the design of the depot involves lots ofmatters inwide range and ismuch affected by the depotsite, the connection condition of the lines forentering into and departing from the depo,t the line and network plan and the resource sharing. Therefore, the overall analyses should be made in the design and the design scheme should be optimized. The pipelines of the depot should be well designed in overall arrangementbecause there are lots of pipelines for the power feeding, overhead contactwires, signaling and communication andwater supplying and draining for the depo.t The large -sized equipments, such as vehicle washing machine and sprocketmachine, much affect the design and construction of civil engineering due to the long production period for them, so it isnecessary to purchase them in advance. The vehicle lifting jacks and vehicle traverse should be used for the overhau,l and it is good for the coming construction ofother facilities for the overhaul.
