yeah it sure did...I guess not many people use a waybill system...maybe they do not see the need or maybe do not understand it or dont run operating sessions. An big advantage of having one...is having an inventory of your rolling stock and locos....hmmmm.....I am surprised of how this quickly lacked interest....
I don't think that it's from a lick of interest, so much as a lack of knowledge and/or experience with "formal" op sessions.
Since the mid 1970's I learned operations and have participated in them using the car cards. I've even used tab-on-cars, colored thumb tacks, and even have used a computer based waybill system.
It is a program called COSS,(Computer Operated Software System), that generated waybils for each car at the start of the session. Setup was just like any system you use. You had to determine which industry, needed what car and at what time and where the destination was, On layout, Off layout, yards, etc. When told the # of waybills to generate, it would do so. Only "bad" part was you had to "manually" decide which trains got which waybills. Best part, it was free, and has been in use since before there were programs like this on the market. It was written by a good friend who is no longer an MR, but it still works.
There is also switchlist generators TAG being one. The program was offered in an issue of MR way back in the mid '80s, but you had to type the program in yourself. It was originally written by Robert Fink and still is being used around the country today. It ran/runs in DOS.
Switchlists are different from waybills in one big way. You only carry one piece of paper that give you reporting marks, car types and destinations. It will also give you a list of pick-ups based on which train you are, and where you're going.
Rex uses Rail-Op, which seems to me to be the best system out there. There is a demo available for download, (free), and you can "run" an op session using the info in the demo, but you can't change anything in the system. You can view the system and what it can do at
