COst-Reducing Dynamic Electrification gradient System (CODES)

目前，英国42%的线路铁路网实现了电气化，其中4238公里使用架空电气化基础设施（2018/19年公路和铁路办公室）。根据网络铁路公司的计划，电气化是一个积极的商业案例。然而，英国滚动计划的预计成本约为每单轨道公里250万至350万英镑，而德国通常为每条轨道公里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高达40%。作为回应，Furrer+Frey提议在GCRE开发一个物理梯度动态系统，该系统将允许快速、真实地复制当前和拟议的电气化梯度，以便在现实世界中测试列车和电气化界面的动态测试，以减少对民事干预的需求。Furrer+Frey模型显示，通过更好的测试，至少20%的对近期主要电气化项目的民事干预可以被消除。CODES项目（降低成本的动态电气化梯度系统）旨在允许我们和Network Rail创建现实生活中的铁路基础设施双胞胎，因此可以在测试环境中快速，经济有效地测试不同的梯度。规范将节省测试成本，缩短项目工期，通过消除民事干预减少铁路电气化成本，也减少了架桥的隐含碳。

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.
