The Mechanical Reference Repository (MRR) centralizes and automates elements of the AAR Interchange Rule 88 and Running Repair Agent (RRA) processes in a single, easy-to-use application. Car mark owners, shop owners, and railroads can reduce the amount of time and manual work required to complete these processes.
Rule 88 establishes minimum mechanical requirements for the interchange of freight cars, as well as the process and documentation required when repairing, rebuilding, or otherwise modifying a freight car. The MRR Rule 88 module enables users to electronically submit Rule 88 applications and supporting documentation, view the status of their applications, manage updates, and store and search applications.
MRR also allows sponsoring railroads to submit associations with Running Repair Agents at specific locations for approval by the AAR. Approved associations are displayed in FindUs.Rail in real time and before they appear in printed quarterly updates.
