Terminal dwell and car velocity remain stable, and we once again saw fuel efficiency gains, attaining a new quarterly record. While not big in Q3, we started to see some of the revenue erosion from competitor reactions to the merger announcement. We're on a good path, and we're doing what we can on the controllable side to prepare for growth. Relative to 2024's full-year results, our year-to-date safety figures demonstrate FRA personal injury ratio has improved 7.8%, and our train accident ratio has improved 27.7%.
Turning to slide six, we achieved stronger service and volume growth this quarter while operating with fewer assets and resources. Operational metrics confirm the effectiveness of our fuel management strategy, which delivered an all-time quarterly record of 1.01, a 5% year-over-year gain. In the quarter, we deployed a new inspection portal in Virginia, bringing the total now to eight. Now let's go to slide 10, where you'll see that we achieved 2% year-over-year growth in both revenue and RPU in the quarter.
Overall, our volume for the third quarter finished flat despite gross ton mile growth of 4%. Volume grew 6% from a year ago, driven by our auto, chemical, and metals, and construction markets. Revenue less fuel grew 7%, which underscores our pricing discipline and our volume performance. However, we had mixed headwinds from growth in commodities such as natural gas liquids, sand, and scrap metal, which diluted our overall RPU performance.
