Improved power supply betters street railway service

This is a distinctly “different” type of discussion of a study of the economic and social results of a 4 years´ use of automatic and supervisory control on the power supply system of the Cincinnati Street Railway. It is written from the viewpoint of an executive or an operating engineer, accurately reflects operating experience, and is designed to be of assistance to those who may be contemplating similar developments. It touches upon several extensive topics of which space prohibits development, but the recognition should be thought-provoking.
