The initial plan of Equipment EI-0001 was to escalate cars to severity level XX (restricted at interchange) that have not moved or are more than 2 years overdue for periodic air brake testing. In September 2023, the Arbitration and Rules Committee voted to change the initial focus to those cars that are overdue and have not moved in over 1 year. There are 30,000 cars that will be escalated to XX severity level by Wednesday, September 04, 2024.
