Rail Car Coupler Redesign

The current type E Janney coupler has not been significantly modified since the original patent was filed in 1873. Couplers that fail while in use cause major delays costing rail companies and customer’s time and money. Alternative materials are being considered to increase fatigue life and decrease weight. This Senior Design team has researched the current failure modes, potential design modifications and potential changes in materials. The type E and corresponding redesigned knuckles from alternative materials will be prototyped and tested to validate initial findings.
