Inscription.  Built by the Illinois Central railroad at it's Burnside shops in Chicago with the instruments provided by the University of Illinois (the car was jointly owned). The dynamometer car is a rolling laboratory that tests the pulling power of locomotives. The front coupler is attached to the frame by a hydraulic cylinder. The pull of a locomotive moves a piston in the cylinder and measuring instruments in the car record data. The system is so sensitive it can detect the forces of a person pulling on the coupler and so strong that it tested an engine pulling a 213 car coal train. Number 30 is 60 feet long, weighs 125,000 pounds and contains an operating compartment with recording table, instruments and tool bench, 2 staterooms which accommodate 4 people each, toilet, shower and kitchen. This car was last used behind a steam locomotive in 1952 and was only used once behind a diesel-electric in 1955. Donated in 1969 by the Illinois Central Railroad and University of Illinois.
