My first job out of college was at Bechtel Engineering in San Francisco and worked in the Refinery division Designing Plant Models to check locations and piping. Some of them were 3-4,000 square feet at 1/4" scale and always though how cool it would be to run some trains through them. One of my Engineers was a quarter scale trolley builder and he would set up loops of track from time to time and chug around the model. Anyway, running or not, this model is an amazing piece of work and focus. Thanks for sharing.
