NOTE: “Trains Active Under the Waiver” List Published to FRA each Friday by BNSF Railway as Supplement to Extended Haul Train Spreadsheet

COLD WHEEL REPEATERS UNDER THE WAIVER: We have seen 78 Cars Repeat Fail within 30 days of failing the BHE Test . 78/1242= 6.3% That gives us 93.7% go on without a repeat failure within 30 days. Of those that had repeated we have seen 2 fail a second time. 2/78=2.6% of the repeaters are a 2nd time repeater

We just added the Hot Valves to the Repeater report on 3/4/2020 to be able to have repeat hot valves looked at and have an ASCAT performed.

Topics for Discussion & Decisions:

• Expansion of BNSF BHE program a Northern Tier operations (BNSF )

• Expansion to other locations outside of California and Chicago for the operations on BNSF’s

• The possibility of adding the “Valve Age” to the information collected when components are changed as a result of an ASCT

• The possibility of adding ambient temperature to the data being collected

• Moving one of the current detectors on the Southern Transcon (Gallup Sub) to a new location to support better braking opportunities and compliance with the Form C
