Eric J. Gehringer
Executive Vice President, Operations at Union Pacific
Thank you, Kenny, and good morning.
Moving to Slide 13. To start, I want to express my appreciation to the team for their relentless focus on improving our service product and driving network efficiency. It's thanks to their efforts that our network showed tremendous fluidity and reliability during the fourth quarter. Freight car velocity improved 14% to 217 miles per day compared to fourth quarter 2022. Increased train velocity and a reduction in terminal dwell drove that performance.
Service was strong during the quarter, as we saw a significant 12-point improvement in both intermodal and manifest and auto trip plan compliance. In addition to trip plan compliance, we have hundreds of customer-specific performance metrics that also showed great improvement throughout the quarter. Most importantly, we are delivering the service we sold to our customers, which is critical to our long-term growth strategy.
While winter is here and has certainly brought its challenges, the railroad overall is very healthy and I'm confident the team will continue its positive momentum. Safety continues to be the foundation of everything we do. During the quarter, we delivered improved derailment performance through our investments in technology and process. We remain focused on the critical actions that drive real change, so everyone goes home safely each day.
Now, let's review our key efficiency metrics for the quarter on Slide 14. During the fourth quarter, we saw a year-over-year improvement across all of our efficiency metrics. Locomotive productivity improved 14% versus fourth quarter 2022 and 9% sequentially, as we continued to identify and execute on opportunities to utilize the fleet more efficiently. Throughout the second-half of 2023, we stored nearly 500 units from our operable fleet. Workforce productivity improved 4% compared to fourth quarter 2022. With a strong crew base, we are focused on effectively managing workforce levels to the demands of the business. However, challenges do remain from scheduled work agreements that, in the near-term, require additional employees.
Train length improved 2% compared to fourth quarter 2022, as we continued to remove car touch points from the system. In total, throughout 2023, we were successful in extending train length as improvements in the second-half more than offset the declines in intermodal shipments. We remain persistent in our focus on train length to drive productivity, while providing a better service product to our customers.
As we move into 2024, we will continue to transform our railroad through a variety of technology initiatives and targeted capital investments designed to further improve safety, improve our service product, enhance resource utilization and, ultimately, lower our cost structure.
So, to wrap-up, let's review our capital outlook for 2024 on Slide 15. We are targeting capital spending of $3.4 billion in 2024. Similar to 2023, we will support safe and productive operations by investing in our infrastructure and renewing our older assets. This includes modernizing locomotive and acquiring freight cars to support replacement and growth opportunities. We are also investing in technology and terminal and mainline capacity projects to improve productivity.
Specific to our technology investments, we recently cut-over net control, replacing our 50 year-old transportation management system. This cut-over positions us to use real-time analytics to open new capabilities for Union Pacific and our customers. Great work, led by our technology team. On the growth front, we will continue to invest in projects that expand our intermodal footprint and support business development and targeted high-growth areas, such as Inland Empire, Kansas City and Phoenix to name a few.
So, with that, I will turn it back to Jennifer to lay out our initial financial thoughts for 2024.
