|The complete transformation of the ICT domain driven by 5G network princi-ples and capabilities, will impact significantly the path towards digitalization of many vertical industries, with modern railway transportations being one of them. In this context, Future Railway Mobile Communication System (FRMCS) service requirements and system principles are very well mapped to 5G service and network concepts associated with network performance, tech-nology neutrality at various levels as well as network planning and deployment options. However, the flexibility of 5G networks implies that concepts are pinned down to deployment paradigms so that afore assertions are proved. The 5G-PPP project 5G-VICTORI aims at delivering a complete 5G solution suita-ble for railway environments and FRMCS services, along with experimentation deployments for testing and evaluation in operational railway environments. This paper discusses the service Key Performance Indicators (KPIs) and tech-nical requirements and provides an overview of the proposed experimental de-ployment in an operational railway environment in the area of Patras, Greece.|
