I've had a play with AI animation of the figures and road vehicles at Farthing. Here's a short video showing the results.
It won’t be to everyone’s taste, but after seeing a few animated model railway scenes pop up recently I had to satisfy my curiosity. I selected a handful of layout photos and asked the software to animate them with descriptive prompts. I didn't apply it to locos and stock as that doesn't appeal to me. I want to run my trains for real :-)
