Interurban test-car of the University of Illinois

About 15 years ago the first serious consideration was given to railway testing work by an educational institution when one of the universities of the middle West∗ installed a locomotive-testing plant. Shortly after, the University of Illinois obtained its dynamometer car, which was in service for some years and was later replaced by a second car having many improvements over the original one. This car is now operated jointly with the Illinois Central Railroad. It was used at the time of making the recent exhaustive investigations for the electrification of the New York Central Railroad. The knowledge acquired from the above mentioned sources has been of much value both commercially and educationally.
