INNOVATIONS IN FROG AND SWITCH DESIGN

Innovations in special trackwork design and development by Canadian Pacific are described. This involves special switch designs, new designs of railbound manganese spring frogs and investigation into the design and use of swing-nose frogs. These are used on single-track mainlines used by many unit trains with total traffic of 50 million gross tons per year. The result has been a main line turnout that has a significantly longer service life with reduced maintenance costs.
