Most model makers leave their signature somewhere in each model. Our depot agent's office is reproduced authentically, with actual artifacts. The agent controlled trains coming through his town and the depot was a gathering place in most communities. The semaphore replaced the railroad high ball signal and works on the same principle as traffic lights. In the case displaying railroad china are dishes from different rail lines.
Full sets are obviously more expensive.
The model of the Aerotrain has an interesting background. General Motors built the model for a trade show and thought it had been destroyed afterwards, but it was saved by an employee who stored it in his basement for years. The original designer, Chuck Jordan, retired in 1992. General Motors came to Green Bay, picked up all 10 cars and the locomotive, took them to Detroit and used them for Jordan's retirement festivities. Picture taking is allowed everywhere, except for flash shots during theater presentations.
