TTX Company provides railcars and related freight car management services to the North American rail industry. Pooled railcars are for service in the intermodal, automotive, lumber, machinery, building materials, steel, and other commodity groups where flatcars, boxcars, and gondolas are required.

TTX Company’s stock is owned by North America’s leading railroads who are also their primary customers. Cars are provided to railroads at competitive car hire rates. Over the past ten years, TTX has invested 3.9 billion in new railcar purchases (61% for intermodal cars).

Chicago is a natural location for the company’s headquarters, as it is the only gateway where all six Class-One North American railroads can interchange traffic.  Fifty percent of U.S. rail freight passes through Chicago's rail yards and 500 freight trains and 37,500 carloads of rail freight (i.e., 2.5 million tons) leave Chicago each day.

The company retained space at 101 N. Wacker after considering a move to suburban Chicago.  Stalled talks were revived between TTX and landlord Equity Office after TTX began scouting properties in Rosemont. Planning Department spokeswoman Connie Buscemi said work was done to “ensure that an equitable deal could be reached that would keep TTX in the city.”

Under Mayor Daley’s leadership, the City of Chicago has invested $11 billion in public infrastructure since 1989, to ensure Chicago’s preeminence as a leading global city for the future.  This investment made a difference to TTX.

President and Chief Executive Andrew F. Reardon acknowledged Mayor Daley’s influence in the decision to remain in Chicago. "The mayor played an active role in our thinking," he said.

Chief Executive Andrew F. Reardon declined to comment about the financial terms of the lease but said, "It's a very tenant-friendly environment right now."

The company has renewed a 15-year lease at 101 N. Wacker and is doing well. TTX had revenue of $1 billion in 2004 and is one of the largest privately held firms in the city of Chicago.
