T²IMS: train-based monitoring system

Good asset management requires good up to date information about the condition of assets and their use. Measurement of train and track related information on board a rail vehicle provides information about train and track interaction which is not provided by other measurement techniques.

How we can help

Lloyd's Register, in cooperation with various companies, developed the on-board Train Track Interface Monitoring Systems (T²IMS), an advanced train-based measuring system for detecting and making train and track related measurements. Using the system we can support asset management programmes, carry out analyses, perform data mining and generate real-time warnings and notifications.

The system has the following key features:

• Accurate real time data transmitted to a central server
• Measurement of track position, train location, energy usage and tracking of low adhesion
• Can be configured to measure particular train-related parameters required by a client
• Measurements made automatically without affecting the train operation
• Advanced digital data analysis translates measured data into client information such as defect reports, maintenance advice, energy charge and other reports.

What are the benefits?

• Improved data and associated analysis improves asset management decision making
• Optimized approaches to maintenance and renewals
• Reliable in-service data can influence modification plans, renewal strategies and specifications for new track and rolling stock - the point at which critical decisions can have a long term effect on availability, performance and cost.

Recent projects

Lloyd's Register carried out a pilot project for Dutch infrastructure manager ProRail with a view to replacing measuring vehicles and periodic visual inspections with the T²IMS system. The system was fitted on board a passenger train along with a GPS positioning device in order to evaluate track geometry. When defects are detected by the system, reports identifying the nature and location of the defect are transmitted from the train to a base station. Currently, plans are being developed for a broader roll-out of the T²IMS system across the NS Dutch Railways fleet.
