Executive Vice President & Chief Financial Officer at Westinghouse Air Brake Technologies
Thanks, Rafael, and hello, everyone. Turning to slide eight, I will review our third quarter results in more detail. We delivered another good quarter of operational and financial performance from strong underlying momentum across the business, coupled with great execution from the team. Sales for the third quarter were $2.55 billion, which reflects a 22.5% increase from the prior year. Sales were driven by strong growth across both the Freight and Transit segments. For the quarter, GAAP operating income was $370 million, driven by higher sales and focused cost management. Adjusted operating margin in Q3 was 17.9%, up 1.5 percentage points versus the prior year.
The increase during the quarter was driven by significantly higher sales, improved productivity and cost management, partially offset by manufacturing inefficiencies driven by the strike at our Erie facility. GAAP earnings per diluted share were $1.33, which was up 51.1% versus the third quarter a year ago. During the quarter, we had pretax charges of $13 million for restructuring, which was primarily related to our Integration 2.0 initiative to further integrate Wabtec's operations and to drive $75 million to $90 million of run rate savings by 2025. In the quarter, adjusted earnings per diluted share were $1.70, up 39.3% versus prior year. Overall, Wabtec delivered another strong quarter. We outperformed our expectations, demonstrating the underlying strength and momentum of the business.
And as a result, we are fine-tuning our full year outlook by increasing our sales and adjusted earnings guidance. Now turning to slide nine. Let's review our product line in more detail. Third quarter consolidated sales were very strong, up 22.5%. Equipment sales were up 38.8% from last year due to higher locomotive sales, which as planned, were significantly skewed to Q3 versus Q4, along with increased demand for mining products this quarter. Components sales were up 32.3% versus last year, largely driven by higher North American OE railcar build and market share gains in Freight car product sales, along with increased demand for industrial products. Sales also benefited from the strategic acquisition of L&M late in the second quarter by $42 million. Digital Intelligence sales were down 3.2% from last year, which was driven by a softness in our North American signaling business, partially offset by higher demand for international PTC, next-gen onboard locomotive products and digital mining.
Our Services sales grew 17.6%. Sales growth was driven by higher modernization deliveries and increased part sales. Our customers continue to recognize the superior performance, reliability, efficiency and availability across their Wabtec locomotive fleets. Across our Transit segment, OE and aftermarket sales significantly increased versus last year. Segment sales were up 20.0% to $660 million behind execution of our growing backlog, easing of supply chain disruptions and comparing against the cyber impact in Q3 2022. The momentum in this segment is strong across our core markets as secular drivers such as urbanization and decarbonization accelerate the need for investments in sustainable infrastructure. Moving to slide 10. GAAP gross margin was 31.0%, which was down 0.1 percentage points from Q3 last year, while adjusted gross profit margin was up 0.1 percentage points driven by higher sales and improved productivity, partially offset by inefficiencies related to the strike in Erie.
Mix was favorable, driven by a richer mix between and within segments. Raw material costs, while still elevated, were largely flat on a year-over-year basis. Foreign currency exchange was favorable to sales by $32 million or 1.5 percentage points and it improved our third quarter gross profits by $7 million. Finally, manufacturing costs were positively impacted by favorable fixed cost absorption and benefits of Integration 2.0, more than offset by manufacturing inefficiencies, primarily at our Erie facility. Our team continues to execute well to mitigate the impact of continued cost pressures by driving operational productivity and lean initiatives. Turning to slide 11. For the third quarter, GAAP operating margin was 14.5%, which was up 2.0 percentage points versus last year. While adjusted operating margin improved 1.5 percentage points to 17.9%. GAAP and adjusted SG&A were $295 million. Adjusted SG&A as a percentage of sales was 11.6%, down 0.7 percentage points versus the prior year as we leverage higher sales and strong focus on managing costs.
Engineering expense was $53 million, about flat with Q3 last year. We continue to invest engineering resources and current business opportunities, but more importantly, we are investing in our future as an industry leader in decarbonization and digital technologies that improve our customers' productivity, capacity utilization and safety. Now let's take a look at segment results on slide 12, starting with the Freight segment. As I already discussed, Freight segment sales were very strong for the quarter, up 23.4%. GAAP segment operating income was $327 million for an operating margin of 17.3%, up 2.1 percentage points versus last year. Adjusted operating income for the Freight segment was $399 million, up 30.0% versus prior year. Adjusted operating margin in the Freight segment was up 1.3 percentage points from prior year at 21.2%.
The increase was driven by significantly higher sales, including fixed cost absorption and lower SG&A as a percentage of revenue and improved mix, somewhat offset by manufacturing inefficiencies driven by the strike at Erie. Finally, segment multiyear backlog was $17.61 billion, down 8.1% from the end of Q3 last year. We continue to compare against the multiyear modernization and locomotive orders totaling over $1.5 billion that we received in 2022. The 12-month backlog was $5.28 billion, up 15.7% for the same period and shows good momentum well into 2024. Turning to slide 13. Transit segment sales were up 20.0% to $660 million. When adjusting for foreign currency, Transit sales were up 14.5%. GAAP operating income was $68 million, up 28.3%. Restructuring costs related to Integration 2.0 activities were $10 million in Q3. Adjusted segment operating income was $83 million, which was up 38.3%. Adjusted operating income increased as a result of higher sales, favorable mix, benefits from our Integration 2.0 activities and the cyber impact in Q3 2022.
This resulted in adjusted operating margin of 12.5%, up 1.5 percentage points from last year. Finally, Transit segment multiyear backlog for the quarter was $3.87 billion, up 12.6% versus a year ago. Now let's turn to our financial position on slide 14. Q3 cash from operations was $425 million versus $204 million in the prior year. Cash flow benefited from higher earnings and improved inventory management. Our debt leverage ratio was 2.1 times at the end of the third quarter, which was favorable versus prior year. And finally, we've returned $344 million of capital back to shareholders year-to-date through share repurchase and dividends. During the third quarter, we utilized free cash flow to pay down debt and reduce leverage after the $229 million acquisition of L&M in the second quarter of 2023. As you can see in these results, our financial position is strong, and we continue to allocate capital in a balanced strategy to maximize shareholder returns.
With that, I'd like to turn the call back over to Rafael.
