UI (Universal Interlocking) is a radical new approach to railway signalling and safety, based around the repeated application of simple, repeatable units in both software and hardware. Each unit is identical, with a set of simple properties and rules, and it's function assured once. When the units are linked sequentially, the effect is to replicate the functions of traditional megalithic route-based interlockings. UI can monitor train speed, position, and integrity, including as overlay, when other systems are fitted. It is robust and fault tolerant, through massive redundancy, and in areas of limited communications, only capacity is reduced, not safety.UWAP (Universal Worksite and Access Protection) takes UI further by allowing trackside staff to interact with the system to unambiguously set up possessions, access worksites, place instant speed restrictions, Emergency Stop all trains/work, and more.Though noting UI could have all the functionality of ETCS, our original development goal was fast deployment to isolated branches, Beeching reopening's and overseas, with a target CapEx and OpEx cost at 10% of competitors.We believe the direct benefits of UI to GCRE are threefold:1. Due to the passive track-borne elements, UI can be fitted as an overlay to other systems without interference. This is key for GCRE as UI can be placed as overlay and fall-back system for when testing other signalling and control system integration. It can maintain an assured independent data of all trains and workforce if systems on test have issues.2. Managing multiple site teams - potentially from many different countries and systems - will be a risk through build, commission and test - especially so on the infrastructure loop. UWAP can provide unambiguous protection, and it is easy to understand through it's human-centric design philosophy.3. With an independent and assured vehicle information feed, UI and UWAP could form the basis of a system independent of onboard signalling required for later automated train testing work, though there would be some train integration work required for full remote ATO.Establishing the 'why' and 'how' of these points are the main elements of the study. The algorithms have been demonstrated Hardware-In-The-Loop in a lab, and key hardware elements are already rail-proven. There is low technical risk. Early engagement and integration will help yield full benefits, and this study is key to that.

UI（通用联锁）是一种全新的铁路信号和安全方法，基于软件和硬件中简单、可重复单元的重复应用。每个单元都是相同的，具有一组简单的属性和规则，并且它的功能得到了保证。当这些单元按顺序连接时，其效果是复制传统巨石路线联锁的功能。当安装其他系统时，UI可以监控列车速度、位置和完整性，包括作为覆盖层。通过大量冗余，它具有强大的容错能力，在通信有限的地区，只会降低容量，而不会降低安全性。UWAP（通用工作场所和访问保护）通过允许轨旁工作人员与系统进行交互来进一步提升UI，以明确地设置财产、访问工作场所、设置即时速度限制、紧急停止所有列车/工作等。尽管注意到UI可以具有ETCS的所有功能，我们最初的发展目标是快速部署到孤立的分支机构，Beeching重新开放的和海外，目标资本支出和运营支出成本为竞争对手的10%。由于采用了被动式轨道元件，UI可以作为覆盖层安装到其他系统上，而不会受到干扰。这是GCRE的关键，因为在测试其他信号和控制系统集成时，UI可以作为覆盖和回退系统。如果测试中的系统出现问题，它可以保持所有列车和劳动力的可靠独立数据。管理多个现场团队-可能来自许多不同的国家和系统-在构建、调试和测试过程中将是一种风险-尤其是在基础设施循环中。UWAP可以提供明确的保护，并且通过其以人为中心的设计理念很容易理解。有了独立和可靠的车辆信息反馈，UI和UWAP可以形成一个独立于车载信号的系统的基础，用于以后的自动化列车测试工作，尽管完全远程ATO需要一些列车集成工作。这些算法已经在实验室中进行了硬件在环演示，关键硬件元素已经过轨道验证。技术风险低。早期参与和整合将有助于产生充分的效益，这项研究是关键。
