The purpose of this study was to develop a cost-effectiveness model which could assess the return on investment (ROI) obtained when energy storage devices or regenerative substations are applied to real transit properties with regenerating trains. The storage devices can either be flywheels or batteries and can be placed off-board or on-board. To c

In December 1973, Congress enacted the Emergency Daylight Saving Time Energy Conservation Act of 1973 which placed the nation on Year-Round Daylight Saving Time for a two year trial period starting Jan. 6, 1974. While energy savings was the main purpose other benefits in safety and crime were also considered to be possible effects. The Act required
