Class 1 rail operator Norfolk Southern is advancing its fleet modernization plan by adding 40 new locomotives, saying they will provide fuel efficiency, reduced emissions, enhanced reliability, and crew comfort.

The engines from Wabtec mark the railroad’s first new locomotive purchase since 2022, and are expected to be delivered in the second half of 2026.

According to Norfolk Southern, the model ES44AC locomotives add reliability by using the newest generation of control systems, which enable real-time remote diagnostics and live operational views, like an IT department accessing a computer screen. This innovation will help reduce delays by spotting potential issues before they become larger problems.

With about 1,600 high-horsepower locomotives currently active, this investment ensures Norfolk Southern remains highly competitive and continues delivering on customer goals efficiently, the company said.
