Think through this development curve for a moment. We have model railroad manufacturers that have told us that they see the hobby going away if things can't be manufactured in China, tariffs, etc.
But the other futuristic view is that the amount of labor needed to make trains drastically decreases due to technology like this. The on-shoring cost for something like this, plus some tooled components like trucks, couplers, and wheels, turns a 20 year ramp up project into 3-5 years.
