The laboratory was established in 1998 to train Illinois Department of Transportation personnel and contractors in the integration and working relationship of the railroad and highway signal systems and has been continually updated since then.
The TOL has about 7,400 sq. ft. of available building space nearly half of which is comprised of offices, classrooms, and testing areas, and the rest is a 17-foot high bay area.
