What’s going to happen to 920-922?

I was up in San Jose last December hoping to get one final glimpse of the F40's when I noticed that 922 was on a south county connector, I also noticed 922 was siting in Gilroy with some MP36's along with 920, and im assuming 921 will or is there with them, are they going to be used on SCC's? Or are they going to be used as rescue engines? Or something else? I know Caltrain isn't selling them to Peru because they only sold 19 F40's.
