Railroad operation?

There are all sorts of lists out there some are more prototypical than others some are organized better than others.

It also depends what you mean by a "switch list’. Ther is the list that yard crews use to classify tracks and then there is the list that industry jobs and locals use to switch industries. The two look very different and serve very different purposes.

Most commercial switchlists are exclusively the industry job type and it is a very small number that generate the class yard switch lists.

Thanks Larry, Actually I’ve been using JMRI for decoder programming but never looked into the operations support. I’ll definitly give it a try. - Bill
