欧洲许多铁路在应用电子计算机开发铁路运营管理信息系统的过程中,先后按X.25标准建立了铁路公用数据分组交换网。为了适应国际联运和旅客列车座席预约业务信息处理和信息交换的需要,在UIC(国际铁路联盟)组建原HERMES(欧洲铁路国际信息网络)之外,欧洲有关铁路根据相应的协议,把各相邻铁路的公用数据网络互连起来,建立泛欧铁路互连数据网络,称之为EURADAT网络。 EURADT网络,是从德国铁路与相邻铁路数据网络互连开始的。欧洲各国铁路基本上或原则上都同意参加EURADAT网络,作为这一网络的成员。
Many European railways in the application of electronic computers to develop railway operation and management information system in the process, has set up by the X.25 standard public railway packet data network. In order to meet the needs of information handling and information exchange of international intermodal and passenger train seat reservation services, in addition to the original HERMES (European Railway International Information Network) formed by the UIC (International Union of Railways), the relevant European railways, according to the corresponding agreement, The public data networks of the railways are interconnected and a pan-European railway interconnection data network is established, termed the EURADAT network.
