Three Way Switch

Currently the CALS track is approximately 30 years old and most of the existing track is nearing its life expectancy and re-building of 30 plus switches is necessary. In the process of installing new track the board members discussed additional improvements to the current track layout. Two major concerns were to implement an additional loading track that would facilitate easier loading access for members to use at the clubhouse and an improved signaling system for operator and passenger safety. The two main lines will be moved over and a loading track substituted at the original outer loop alignment creating a shoefly effect.

The CALS board of directors determined that a 3-way switch would be required to implement this improvement. During the initial design of the three (3) way switch it was necessary to do some research on the prototype practice. A trip to the Strasburg bookstore resulted in mentally extracting a paragraph from a track workbook pertaining to 3 way switches. Since there was so little information available, we decided that it was not necessary to purchase the text. The first step in fabricating the three-way was designing the crotch frog. Then the two standard frogs and the crotch frog was machined.

The fabrication and assembly of the 3-way switch consisted of approximately 10 hours of pre-assembly machining and design and 20 hours of actual assembly of the track layout, and installation of 90 ties, 850 screws, and washers.

This proved to be an outstanding work day! Cool weather and plenty of help. The CAL's crew installed the three-way switch, thirty feet of straight track, and a regular switch. Everyone had a sense of pride and satisfaction from a job well done. Fellowship with regulars was great -- come join for the next project. All Hands Welcome! Ladies, too.

What's next?

The double slip switch for the yard sounds like a good project
