Trains for public transit systems all across the United States are built on the west side of Salt Lake City.

The company that builds them, Swiss firm Stadler, celebrated the expansion of its Utah plant near 5600 West and Interstate 80 this week. Stadler also marked its 10th year of operations in the U.S.

Swiss President Guy Parmelin, Gov. Spencer Cox and Senate President Stuart Adams, R-Layton, were all in attendance.

The new addition to the facility will help the firm construct and sell more zero-emission trains, officials say. In total, the expansion included two new assembly halls, welding and sandblasting facilities, and a train battery charging station.

The plant is currently working on railcars for Northern California’s Caltrain system, Atlanta’s MARTA network and the Chicago area’s METRA commuter rail lines.

Stadler will also build new TRAX Blue Line trains for use in its own backyard.

Here’s what the plant looks like inside:
