In the January and February 2005 issues of OGR, Rich Melvin discussed a new time line oriented control system which would work with TMCC, DCS and DCC. It was called Time Line Command from a company named Creative Trains Company.
It let you control the accessories on your layout in a time sequence so you could script a simulation of a complete day of life on your layout with lights and accessories operating at different times during the simulated day.
I looked at the Wayback Machine web page and was able to find a March 2005 copy of the OGR webpage. Here are the two columns by Rich Melvin about the system:

Does anyone know what happened to this system? The technical details were available at the time but don't appear on the Wayback Machine's archived page.
