Call for Comment

C-13388
Solicitation of Comments for Revisions to MSRP Section D (TRUCKS AND TRUCK DETAILS), Specifications M-976 Truck Performance for Rail Cars. Addition of Traction Ratio Test
Issued: August 1, 2019
Effective: 30 days for comment

Consistent rolling resistance test results have been difficult to obtain due to the susceptibility of the method to environmental conditions including wind and wheel/rail coefficient of friction. To help overcome environmental effects on testing and allow testing to be more representative of service speeds, the curve and tangent rolling resistance test in paragraph 4.1.2.2 has been replaced with a new test method, the “traction ratio" test. The proposed draft is attached to the circular.
