YourToyTrains- Model Trains- is proud of our home town- Dallas, Texas. We found these words painted on the side of a building on Commerce Street in the Deep Ellum section of Dallas. Yes, Dallas is NOT on a navigable body of water. Denver might also not be on a navigable body of water, and we love Denver too! Both cities grew with RAILROADS. Yes, a lot of sweat by pioneers who took this raw Blackland Prairie and built a great city from nothing. But the great city could have been anywhere. Dallas became the GREAT CITY of North Texas because main north-south and east-west rail lines crossed here. Plus all that sweat!
