Information Requirements for Railroad Enterprise Asset Management: Practical Approach on Amtrak's High-Speed Northeast Corridor Railway Line

Providing a safe, reliable, and maintainable railway infrastructure is a formidable challenge in Amtrak's complex operating environment. Presented is the design description of the Infrastructure Information Management database, including the latest developments and incorporating vehicle-track interaction measurements. Also shown is how wayside measurements combined with a record of train movement to define the traffic and utilization of the railway infrastructure. An example of the use of the system is discussed to illustrate how the combined information will assist the maintenance managers in determining when and where to invest resources to optimally maintain the railway infrastructure. Also addressed is how wayside and record of train movement can be used to allocate maintenance costs to the various service providers.
