Hi, In about 2 or 3 weeks I will be building a Virtual Reality railroad on the internet. The area of ground covered will be 1,000,000 square meters and include mountains, rivers, cities, towns and of course hundreds of miles of rails and several hundred boxcars,pullmans, observation cars and both steam and diesel locomotives. The era will range from about 1890 (give or take 10 years) thru the 1920s for the most part with one area to be a modern city. I'm thinking that some pretty impressive trestles and tunnels can be built thru the mountain area. Think of the area as being a blank country and everything has to be put in place. Trees, rocks,waterfalls, rivers, homes...even the birds and butterflys. If anyone would like to help with this project you would be very welcome. To the eye all of the objects will appear as full size.
