I am currently involved in a long-running project called Railway(Rail) 3D. The object is to create a freeware program to allow the user to plan, build and simulate a railway network. It allows custom stock, scenery, track, OHLE (electricication) and signals. The program is fully 3D and avaliable at
www.rail3d.net for download. The program is only a few MB. Models are created using a header (defining the paramaters of the object) then using any of a few techniques. Its updated regularly, but we have one problem. We lack people to make new objects! We need your help. If you're interested, why not visit the yahoo group at
www.groups.yahoo.com/group/railway3d !
