An Assessment of the Applicability of Heavy Point Frogs to Joint High Speed Passenger and Freight Operations

摘要

1. It is difficult to comply with FRA Track Safety Standards for Heavy Point frogs in higher speed track. 2. Dynamic simulations show that the frogs can be operated safely with a waiver of track safety standards for Face Gage. 3. A modified heavy point frog was developed that can meet track safety and ride quality standards a. The prototype frog is in test b. Revenue Service testing is planned.
