Targeting digital systems to improve capacity and performance on the railway
A digital railway benefits passengers, freight and the national economy.
Our railway is full in many places.
随着欧洲增长最快的网络，英国的铁路运行了两倍多的乘客，就像二十年前一样。
越来越多的需求意味着20世纪30年代将有十亿额外的旅程。该网络还需要更多的货运列车空间，每年运输30亿英镑的商品，比公路旅行更环保。
Capacity challenges are most acute in many of our major cities, not just London.
Traditional options like building new tracks or extending trains and platforms will not on their own deliver the space for extra trains we need.
满足需求的唯一方法是与传统升级组合部署数字信令和火车控制控制。这将通过使其更加智能，更有效地释放基础架构的能力。
Digital train control systems will help improve the performance of the network to provide passengers with a better experience.
传统的信令和火车控制系统可降低网络的灵活性，在出现问题时努力迅速恢复。铁路的一部分延迟仍然会导致knock-on delayshundreds of miles away on other parts of the network, many hours later.
Traffic management
数字流量管理系统将通过降低延迟以及在发生中断时恢复时间表所需的时间来提高铁路的性能。
Traffic management controls the flow of trains across the network in the most efficient way, maximising the throughput and adapting as network conditions change. It helps to manage disruption and reduce secondary or knock-on delays.
It will also improve passenger information and supports effective timetable planning by developing options for more effective ‘conflict free’ timetables.
In-cab signalling
传统的线条信号传导系统也非常昂贵地安装和维护。尽管其高建和维护成本高，但信号资产失败是延迟的主要原因。2014 - 2015年，有16,228个信令失败，足以影响服务。
数字信令系统删除了大量的轨道身体基础设施，由板载设备运营，该设备被放置在火车驾驶室。这为驱动程序提供了更好的信息，并且更具成本效益。
