Design of Track Transitions: Research Results Digest 79

This digest reviews and analyzes various track transition designs among ballasted and non-ballasted track forms and structures, and offers guidance to improve track and operating performance. The research is based on similar work conducted for freight railroads, modified as necessary, for the transit operating environment. The results should be of interest to engineers involved in the design, construction, maintenance, and operation of rail transit systems.
