As the demand for modern, sustainable rail grows across the U.S., so does the need for domestic manufacturing muscle. From high-speed trainsets to next-gen commuter fleets, a new wave of investment is reshaping the inter-city rail landscape—and it’s happening in places you might not expect.

Here’s a look at the existing, new, and emerging train manufacturing sites powering America’s inter-city rail renaissance.

Legacy Leaders: Where Trains Already Roll Off the Line

• Siemens Mobility – Sacramento, CA

  • Produces Amtrak Airo trainsets, Brightline high-speed trains, and Charger locomotives

  • Full-cycle manufacturing: design, welding, assembly, testing

  • Powered partly by solar energy, with a focus on sustainability

• Alstom – Hornell, Plattsburgh & Kanona, NY

  • Hornell: Builds Avelia Liberty high-speed trains for Amtrak

  • Plattsburgh: Assembles components for national fleets

  • Kanona: Refurbishment and modernization hub

  • Also operates an engineering center in West Mifflin, PA

• Stadler Rail – Salt Lake City, UT

  • Manufactures FLIRT DMUs and KISS EMUs for U.S. and Canadian markets

  • Known for modular, low-floor designs and regional rail innovation

New & Emerging Sites: The Next Chapter in U.S. Rail

• Hitachi Rail – Hagerstown, MD

  • Opened in 2025 to build 800+ railcars for Washington Metro (WMATA)

  • $100M investment with long-term potential for national projects

• Siemens Mobility – Lexington, NC

  • $220M advanced manufacturing facility announced in 2023

  • Will complement Sacramento operations and expand capacity for passenger rail

  • Focused on sustainable production and workforce development

Context for Ohio

As Ohio pushes for better mobility—from expanded Amtrak service to regional rail corridors—these manufacturing sites represent that domestic rail is viable, scalable, and ready.
