Modelling what might have been in southeast BC and northwest Wasington

Car Forwarding Simulation

This is the home page for my Car Forwarding Simulation (CFS) program. For now, it only has this abstract, plus a link to a concepts document describing the program. Both need to be updated somewhat, but they will serve as an introduction to what I am working on.

Traditional computer based approaches to car forwarding on a model railroad can easily generate lots of activity, however the car movements are often random rather than being along a specific route to fulfill a prototypical shipment. These unrealistic car movements are a common criticism of such programs.

Individual Car Cards and Way Bills (CC/WB) on the other hand, can easily represent the richness of prototype shipments, but they require a lot of manual work to create, modify, use, and set up between operating sessions.

I am writing a new computer program to overcome both of these limitations. The first goal is to maintain the richness of the prototypical shipment based CC/WB system while eliminating all of its manual set up work between sessions. 

Secondly, by simulating multiple days, it is easy to compare different operating scenarios as it is all just data inside a computer program. This is very useful for tuning car traffic on an existing layout, and can even influence new or expanded layout design by simulating a layout before it is even built.
