Alstom officially opened its new state-of-the-art manufacturing facility, Plant 4, in Hornell, N.Y., marking a major milestone for U.S. rail manufacturing. 

Spanning 135,000 square feet, the facility is one of the few in the U.S. capable of producing stainless steel car body shells for passenger railcars.

Alstom’s Railcar Investment

The $75 million investment strengthens Hornell’s position as the largest passenger railcar manufacturing site in the country and supports Alstom’s broader commitment to reshoring advanced manufacturing capabilities. 

Previously, Alstom produced these car bodies in Brazil. With Plant 4, the production is now back on U.S. soil, enhancing domestic supply chains and reinforcing New York’s Southern Tier as a hub for rail innovation.

"Plant 4 upholds our long-standing commitment to making trains in America and expands our ability to deliver cutting-edge rail solutions," said Michael Keroullé, president of Alstom Americas. “We’re not just building trains— we’re creating opportunities.”

What’s Next?

The facility is set to launch production on 200 multilevel commuter railcars for Chicago’s Metra system and will support other national rail projects.

 Utilizing advanced robotics and AI-powered automated welding systems, Plant 4 delivers precision manufacturing with tolerances within one millimeter, increasing both quality and cost-efficiency for transit agency partners.

Plant 4 is expected to generate 258 new jobs, including mechatronics and robotics positions, while retaining 390 existing roles. 

Alstom officials said the company collaborated with more than 40 contractors and received support from multiple federal, state, and local agencies, including Empire State Development and the U.S. Economic Development Administration.
