COst-Reducing Dynamic Electrification gradient System (CODES)

目前，英国42%的铁路网络是电气化的，其中4，238公里使用高架电气化基础设施（公路和铁路办公室2018/19）。根据网络铁路计划，电气化有一个积极的商业案例。然而，在英国，滚动计划的预计成本约为每单轨公里（stk）250万至350万英镑，而例如德国，通常为每stk 100万英镑。RIA电气化成本挑战-2019年3月强调，民事干预对电气化总成本的贡献可能高达40%。作为回应，Furrer+Frey建议在GCRE开发一个物理梯度动态系统，这将允许快速，真实地复制当前和拟议的电气化梯度，因此，列车和电气化接口的动态测试可以在真实的世界中进行测试，以减少对民事干预的需求。Furrer+Frey模型显示，至少20%的通过更好的测试，可以消除对最近主要电气化项目的民事干预。CODES项目（降低成本的动态电气化梯度系统）旨在让我们和Network Rail创建铁路基础设施的现实生活双胞胎，因此可以在测试环境中快速，经济和有效地测试不同的梯度。CODES将节省测试成本，缩短项目工期，通过消除民事干预来降低铁路电气化成本，并减少升高桥梁的隐含碳。

Currently, 42% of the UK's routed rail network is electrified, with 4,238km using overhead electrification infrastructure (Office of Road and Rail 2018/19). According to Network Rail plans, there is a positive business case for electrification. However, the projected cost of rolling programmes in the UK is around £2.5 - £3.5 million per single track kilometre (stk) against for instance Germany, it is typically £1m per stk. The RIA Electrification Cost Challenge -- March 2019 highlighted that the contribution of civil interventions to the total cost of electrification can be as high as 40%.In response, Furrer+Frey are proposing to develop a physical gradient dynamic system at GCRE, that will allow rapid, real-life replication of current and proposed electrification gradients, so that dynamic testing of the train and electrification interface can be tested in the real world in order to reduce the need for civils interventions.Furrer+Frey modelling shows that at least 20% of the civil interventions on recent major electrification projects could have been removed through better testing. The CODES project (COst-Reducing Dynamic Electrification gradient System) is designed to allow us and Network Rail to create real-life twins of the rail infrastructure, so different gradients can be tested quickly, affordably and efficiently in a test environment. CODES will save testing costs, reduce project durations, reduce railway electrification costs by removing civil interventions and also reduce the embodied carbon of raising bridges.
