Madison Yard is the Terminal Railroad Association of St. Louis’s major switching facility in Madison, Illinois, and TRRA describes it as the heart of the company’s operations.
The yard sits within the St. Louis freight gateway and supports the movement, sorting, and interchange of large volumes of rail traffic moving through the region.
TRRA describes Madison as its rail switching facility in Illinois, with about 80 inbound, outbound, and holding tracks and roughly 30,000 cars moving through the yard each month.
The yard is not tied to one Class I railroad in the way some freight properties are.
It functions as part of a broader terminal system that connects traffic for multiple major carriers operating in and out of the St. Louis market.
That operating role has made Madison Yard a long-running freight worksite shaped by locomotives, railcar handling, mechanical services, and daily yard activity.
Workers assigned there may have spent years in a heavy railroad environment defined by switching operations, train preparation, and constant freight movement.
