Customer Southeastern Trains Ltd.
London United Kingdom
Southeastern Railway required reliable maintenance and operational support for its Class 707 electric multiple unit fleet to ensure consistent and punctual passenger services across the London commuter network. The customer sought to maximize fleet availability and minimize downtime through efficient depot operations and technical support.
The British Rail Class 707 is an electric multiple unit passenger train built by Siemens Mobility on its Desiro City platform, operated in England - London and Kent (previously operated by South Western Railway from Wimbledon depot)
Comprising 30, five-car electric multiple units - third rail 750V DC supply
Southeastern operates services between London and Kent on several routes using various train types from multiple depots.
Class 707 units are used on Southeasterns metro routes serving London and the Kent commuter belt.
Where early visibility enables informed decisions Southeastern operates one of the UK’s busiest commuter rail networks – connecting London and Kent with communities across Southeast England. Siemens Mobility implemented Railigent X applications that connect live train data with remote condition monitoring and provide near-real-time insights into vehicle health. Teams can assess vehicle conditions earlier, conduct remote diagnostics, and make informed operational decisions – resulting in fewer delays, higher fleet availability, and a more reliable passenger service.
Siemens Mobility provided fleet maintenance services and depot infrastructure support for the Class 707 Desiro City electric multiple units operated by Southeastern Railway. The solution encompassed rolling stock maintenance, technical servicing, and depot management to keep the fleet in optimal operational condition.
Railigent X Fleet Monitoring and Fleet Operations now enables better live view and better in service support and actions and replaces former usage of COM@RL
Hi-tech operating system to ensure reliability across the fleet
Class 707 Golden spanner awards (industry reliability), 3x Golden spanner winner (best performance) 1x Silver spanner winner (most improved)
Services: TSSSA (technical support and spares supply agreement), Digital services / Digital technologies: Railigent X Fleet Monitoring, Fleet Operations CORMAP, Com@RL, MRX (@Ramsgate depot), Snowflake (allows data from all these tools to be pulled into automated dashboards PBI etc)
Better data gives us earlier warning signals and allows us to provide drivers with evidence-based recommendations.
