The TTCI switch point profile design has proven to be effective in revenue service. It provides significant benefit in lower wear and RCF formation rates. Western railroads are planning to implement the profile as a standard design this year.rnThe stock rail profile design requires further development and testing before implementation. The prototypes show promise in being able to affect the location and amount of metal flow on stock rails. After design refinement, this should lead to a longer switch point fatigue life.
