OpsBuddy is a free switchlist building tool designed specifically for smaller model railroads and shelf-style layouts where fewer industries and less traffic is the norm. You can access OpsBuddy here: https://docs.google.com/spreadsheets/d/1y8jbRy0lxMmmrtj_qnKQb1stEQMqq_BGPU02VjTeQmQ/template/preview (NOTE: To save a copy of OpsBuddy, click on the "Use Template" button in the upper right. A Gmail account is required to edit and save the document.)
Feel free to adjust it and make changes to meet your own operational requirements.
OpsBuddy was inspired by the free switchlist template by Bill Neale. His original Excel document can be found here: https://www.trains.com/mrr/how-to/model-railroad-operations/model-railroad-switch-list-template/
If you are interested in a shorter video that gets right into building a switchlist, I've added one here: https://youtu.be/Y5LXidwhleA?si=fmcjho_tEoPlyKix
